Why do you need new spark plugs for your snowblower?

How do you know your snowblower needs new spark plugs? Is your engine start-up inconsistent or slow? Does it seem to take more time than usual to clear your snow? Your snowblower is a big investment. Exposing your engine to unnecessary stress will shorten its running life and devalue your machine. A sluggish snowblower will burn more fuel, and that’s another avoidable hit to your wallet.

Frequently asked questions about snowblower spark plugs

How often should I replace my spark plugs?

For best results, you should replace your spark plugs every 50,000 miles under normal driving conditions.

How do I know if one of my spark plugs is fouled?

If your engine misfires, idles roughly or doesn’t run smoothly, one or more of your spark plugs may have become dirty or fouled.  Other symptoms of a fouled spark plug include a lack of acceleration, reduced gas mileage and difficulty starting.

Do I still need to gap spark plugs?

Pulstar spark plugs should be gapped to the setting recommended by the engine manufacturer up to 0.055” (1.40 mm).  Do not gap greater than 0.055”. For factory turbo or supercharged engines, gap Pulstar spark plugs to 0/025” (0.63 mm). 

What happens if I don’t gap the spark plugs correctly?

An engine with spark plugs that are not gapped correctly will not run smoothly and may not have power or misfire. 

How often should I replace my lawn mower spark plug?

Lawnmower spark plugs are typically replaced once a year.

Does it help to clean spark plugs?

Spark plugs cannot be cleaned enough to operate as new.  It is always best to replace fouled or contaminated spark plugs.

How do I install Pulstar spark plugs?

Pulstar spark plugs install the same way conventional spark plugs are installed.  When using a ratchet and socket or similar tool, care should be taken to not put a side load on the ceramic.

What kind of performance benefits can I expect when upgrading to Pulstar spark plugs?

Customers see significant improvements in engine torque, horsepower, fuel economy and emissions.  They notice quicker throttle response, smoother operation and improved towing capacity.

How do Pulstar spark plugs produce these performance benefits?

The science underlying our technology is sometimes called pulse power: energy accumulated over time is released quickly producing a very high power event, i.e., a pulse. Our patented technology applies this concept by embedding in Pulstar spark plugs a capacitor to store ignition coil energy prior to discharge, and to drive an ultra-high current channel across the gap when released. That powerful current creates an electromagnetic field that expands through the combustion chamber and ionizes the fuel air mixture, allowing the flame kernel to grow much more rapidly than in a conventional spark plug ignition event. The result is the most precise, powerful, consistent and complete burn possible.

Do you guarantee these performance benefits?

Yes, we do.  If you aren’t completely satisfied with your Pulstar spark plugs, return them, together with your dated sales receipt, to the merchant from whom you bought them within 30 days for a full refund of your purchase price.

Do Pulstar spark plugs come with a warranty?

Yes, they do.  If your Pulstar spark plugs prove to be defective in materials or workmanship within one (1) year of purchase, return them, along with your dated sales receipt and an explanation of the reason for the return, to Pulstar LLC, 2451 Alamo Avenue SE, Albuquerque, New Mexico 87106 and Pulstar LLC will replace them.

You can feel the difference

These plugs really walk the walk when you install them. I compared the spark compared to what I had in before and the size of the spark is huge! I had Iridium plugs in before they blew those plugs away! You can feel the difference in the throttle and the way it responds when you punch the gas. I would recommend them to anyone. YES they are pricy but I feel they are worth every penny. I would buy them again any day of the week!

It’s a no brainer

I don't really write reviews… but I felt I had to with these plugs. I researched the website and technology and it made sense. I had no idea a spark plug could make such a difference in performance until now!! I have a 2014 EFI Triumph Bonneville - I have added a ton of performance upgrades and even remapped the fuel injection for more performance... All of the upgrades made a difference.. but none as dramatic - nor a bigger bang for the buck - as swapping out my plugs for these. I will put these plugs in anything and everything I have a spark plug in if possible. To me it's a just a no brainer. Do yourself a favor and get them.

These are not your latest Fad of a spark plug, They work awesome as stated. After all these years of trying every spark plug brand out there. I now am beyond happy with these plugs since I can actually feel the consistent power from zero to my top end. Now the Pulstar's are going in my fleet! I cant wait to try them in my snow machine.

IMMEDIATELY I noticed an improvement

I came across Pulstar spark plugs in some 4x4 enthusiast forums, and after looking through their website I was so impressed with all the background information provided (both the level of scientific analysis, and the sheer volume of empirical data) that I decided the generally high-price was justified, and I would try the plugs in my own vehicles (a 1989 Landcruiser and a 1997 4Runner). IMMEDIATELY I noticed an improvement in throttle response; it was particularly obvious in my 4Runner which suffered from an 'engine stutter' issue that I had been trying to properly diagnose and fix for about a year. Right away, the stutter issue went from being noticeable in approx 15-30% of certain throttle situations to scantily noticeable at all, and when it is noticed it's only in approx 0-5% of the same throttle situations. I also noticed a significant improvement in fuel economy. I am almost religious when it comes to calculating my overall fuel economy for the last tank of gas after every fillup (I even know exactly how much my different-than-factory-sized tires impact odometer readings on both of my trucks, based on distance comparisons between odometer vs. GPS data) and prior to changing the spark plugs I would average between 16-18 MPG (often in the high 16s - mid 17s, and only reaching 18+ on tanks that were nearly 100% highway miles at cruising speed) in the 4Runner. Now, since installing Pulstar spark plugs, I've filled-up 4x tanks of gas in the 4Runner (none yet in Landcruiser) - and on the first three (which were no different from my normal weekly commute to/from) I averaged 18+ MPG (up to 18.5) and on the last tank, which admittedly was quite favorable in that it was 260+ miles all on the highway at cruising speed (not more than 75mph) and coming from Bishop CA to Los Angeles CA (an overall drop in elevation of about 3,000ft) I averaged an ALL-TIME-HIGH overall 20.1 MPG!

Distinct improvement in fuel efficiency

The change to Pulstar® plugs gapped to factory 0.035″ was the only change made for this test. We waited for the first tank of fuel to burn through before making comparisons. At that point there were several distinct improvements: Better tip-in throttle response at any road speed and under heavy acceleration. Less throttle needed to sustain normal “cruise” road speeds. Less downshifting on grades with cruise control applied. Acceleration improved with both forced and cruise control downshifts. Distinct improvement in fuel efficiency; approximately one mile per gallon improvement (5.5%) under “city” and “highway” or interstate test conditions; this engine has always started well.  Click here to watch the video.

I have installed these in over 10 vehicles. Always made them run better and in most cases got better mileage. I installed a set in my 2006 GLI. Improved mileage by 2 mile per gallon. When I sold it, I took them out and mileage dropped immediately by 2 miles per gallon. I use these in all my cars and installed them in many of my friends cars and truck. Alos a huge improvement in the dual plugged Dodge trucks but you need to replace all the plugs.

It’s a no brainer

I don't really write reviews… but I felt I had to with these plugs. I researched the website and technology and it made sense. I had no idea a spark plug could make such a difference in performance until now!! I have a 2014 EFI Triumph Bonneville - I have added a ton of performance upgrades and even remapped the fuel injection for more performance... All of the upgrades made a difference.. but none as dramatic - nor a bigger bang for the buck - as swapping out my plugs for these. I will put these plugs in anything and everything I have a spark plug in if possible. To me it's a just a no brainer. Do yourself a favor and get them.

Beyond happy

These are not your latest Fad of a spark plug, They work awesome as stated. After all these years of trying every spark plug brand out there. I now am beyond happy with these plugs since I can actually feel the consistent power from zero to my top end. Now the Pulstar's are going in my fleet! I cant wait to try them in my snow machine.

IMMEDIATELY I noticed an improvement

I came across Pulstar spark plugs in some 4x4 enthusiast forums, and after looking through their website I was so impressed with all the background information provided (both the level of scientific analysis, and the sheer volume of empirical data) that I decided the generally high-price was justified, and I would try the plugs in my own vehicles (a 1989 Landcruiser and a 1997 4Runner). IMMEDIATELY I noticed an improvement in throttle response; it was particularly obvious in my 4Runner which suffered from an 'engine stutter' issue that I had been trying to properly diagnose and fix for about a year. Right away, the stutter issue went from being noticeable in approx 15-30% of certain throttle situations to scantily noticeable at all, and when it is noticed it's only in approx 0-5% of the same throttle situations. I also noticed a significant improvement in fuel economy. I am almost religious when it comes to calculating my overall fuel economy for the last tank of gas after every fillup (I even know exactly how much my different-than-factory-sized tires impact odometer readings on both of my trucks, based on distance comparisons between odometer vs. GPS data) and prior to changing the spark plugs I would average between 16-18 MPG (often in the high 16s - mid 17s, and only reaching 18+ on tanks that were nearly 100% highway miles at cruising speed) in the 4Runner. Now, since installing Pulstar spark plugs, I've filled-up 4x tanks of gas in the 4Runner (none yet in Landcruiser) - and on the first three (which were no different from my normal weekly commute to/from) I averaged 18+ MPG (up to 18.5) and on the last tank, which admittedly was quite favorable in that it was 260+ miles all on the highway at cruising speed (not more than 75mph) and coming from Bishop CA to Los Angeles CA (an overall drop in elevation of about 3,000ft) I averaged an ALL-TIME-HIGH overall 20.1 MPG!

Distinct improvement in fuel efficiency

The change to Pulstar® plugs gapped to factory 0.035″ was the only change made for this test. We waited for the first tank of fuel to burn through before making comparisons. At that point there were several distinct improvements: Better tip-in throttle response at any road speed and under heavy acceleration. Less throttle needed to sustain normal “cruise” road speeds. Less downshifting on grades with cruise control applied. Acceleration improved with both forced and cruise control downshifts. Distinct improvement in fuel efficiency; approximately one mile per gallon improvement (5.5%) under “city” and “highway” or interstate test conditions; this engine has always started well.  Click here to watch the video.

Tractor spark plugs | Albuquerque, NM

Spark plug replacement is an easy and inexpensive way to keep your tractor operating at peak performance. Depending on how much work your tractor does, you may only need to replace the spark plugs once per season. Experts recommend new tractor spark plugs after every 100 hours of engine operation. Old spark plugs can suffer the effects of exposure to high temperatures. This results in debris build-up and wear and tear that inhibits an effective energy discharge. When you’re looking for tractor spark plugs from Albuquerque, NM, depend on Pulstar for the benefits of standard spark plugs, but with the added performance of innovative new technology.

Frequently asked questions about spark plugs

How often should I replace my spark plugs?

For best results, you should replace your spark plugs every 50,000 miles under normal driving conditions.

How do I know if one of my spark plugs is fouled?

If your engine misfires, idles roughly or doesn’t run smoothly, one or more of your spark plugs may have become dirty or fouled.  Other symptoms of a fouled spark plug include a lack of acceleration, reduced gas mileage and difficulty starting.

Do I still need to gap spark plugs?

Pulstar spark plugs should be gapped to the setting recommended by the engine manufacturer up to 0.055” (1.40 mm).  Do not gap greater than 0.055”. For factory turbo or supercharged engines, gap Pulstar spark plugs to 0/025” (0.63 mm). 

What happens if I don’t gap the spark plugs correctly?

An engine with spark plugs that are not gapped correctly will not run smoothly and may not have power or misfire. 

How often should I replace my lawn mower spark plug?

Lawnmower spark plugs are typically replaced once a year.

Does it help to clean spark plugs?

Spark plugs cannot be cleaned enough to operate as new.  It is always best to replace fouled or contaminated spark plugs.

How do I install Pulstar spark plugs?

Pulstar spark plugs install the same way conventional spark plugs are installed.  When using a ratchet and socket or similar tool, care should be taken to not put a side load on the ceramic.

What kind of performance benefits can I expect when upgrading to Pulstar spark plugs?

Customers see significant improvements in engine torque, horsepower, fuel economy and emissions.  They notice quicker throttle response, smoother operation and improved towing capacity.

How do Pulstar spark plugs produce these performance benefits?

The science underlying our technology is sometimes called pulse power: energy accumulated over time is released quickly producing a very high power event, i.e., a pulse. Our patented technology applies this concept by embedding in Pulstar spark plugs a capacitor to store ignition coil energy prior to discharge, and to drive an ultra-high current channel across the gap when released. That powerful current creates an electromagnetic field that expands through the combustion chamber and ionizes the fuel air mixture, allowing the flame kernel to grow much more rapidly than in a conventional spark plug ignition event. The result is the most precise, powerful, consistent and complete burn possible.

Do you guarantee these performance benefits?

Yes, we do.  If you aren’t completely satisfied with your Pulstar spark plugs, return them, together with your dated sales receipt, to the merchant from whom you bought them within 30 days for a full refund of your purchase price.

Do Pulstar spark plugs come with a warranty?

Yes, they do.  If your Pulstar spark plugs prove to be defective in materials or workmanship within one (1) year of purchase, return them, along with your dated sales receipt and an explanation of the reason for the return, to Pulstar LLC, 2451 Alamo Avenue SE, Albuquerque, New Mexico 87106 and Pulstar LLC will replace them.

You can feel the difference

These plugs really walk the walk when you install them. I compared the spark compared to what I had in before and the size of the spark is huge! I had Iridium plugs in before they blew those plugs away! You can feel the difference in the throttle and the way it responds when you punch the gas. I would recommend them to anyone. YES they are pricy but I feel they are worth every penny. I would buy them again any day of the week!

Snowmobile spark plugs

Keep your snowmobile in top performing condition by changing out your spark plugs on a regular basis. For moderate snowmobile use, one set of spark plugs per season is sufficient. If you’re riding hard and often, be prepared to change out your spark plugs more frequently. Fresh spark plugs keep your engine running its best and give you a better ride over a longer time. For your best snowmobiling experience, Pulstar makes the best spark plugs.

BUY NOW

Does your snowmobile need new spark plugs?

Spark plugs are built to withstand extreme temperatures and high impact. To keep your snowmobile at peak performance, your spark plugs should be in good condition. When deposit builds up or wear and tear expands the space at the piston head, you get ignition lag and a sluggish engine. Only the Pulstar spark plug has novel technology that pumps up your torque and gives you a quicker throttle response. You can trust Pulstar spark plugs because they are made and inspected here in the USA.

Frequently asked questions about spark plugs

How often should I replace my spark plugs?

For best results, you should replace your spark plugs every 50,000 miles under normal driving conditions.

How do I know if one of my spark plugs is fouled?

If your engine misfires, idles roughly or doesn’t run smoothly, one or more of your spark plugs may have become dirty or fouled.  Other symptoms of a fouled spark plug include a lack of acceleration, reduced gas mileage and difficulty starting.

Do I still need to gap spark plugs?

Pulstar spark plugs should be gapped to the setting recommended by the engine manufacturer up to 0.055” (1.40 mm).  Do not gap greater than 0.055”. For factory turbo or supercharged engines, gap Pulstar spark plugs to 0/025” (0.63 mm). 

What happens if I don’t gap the spark plugs correctly?

An engine with spark plugs that are not gapped correctly will not run smoothly and may not have power or misfire. 

How often should I replace my lawn mower spark plug?

Lawnmower spark plugs are typically replaced once a year.

Does it help to clean spark plugs?

Spark plugs cannot be cleaned enough to operate as new.  It is always best to replace fouled or contaminated spark plugs.

How do I install Pulstar spark plugs?

Pulstar spark plugs install the same way conventional spark plugs are installed.  When using a ratchet and socket or similar tool, care should be taken to not put a side load on the ceramic.

What kind of performance benefits can I expect when upgrading to Pulstar spark plugs?

Customers see significant improvements in engine torque, horsepower, fuel economy and emissions.  They notice quicker throttle response, smoother operation and improved towing capacity.

How do Pulstar spark plugs produce these performance benefits?

The science underlying our technology is sometimes called pulse power: energy accumulated over time is released quickly producing a very high power event, i.e., a pulse. Our patented technology applies this concept by embedding in Pulstar spark plugs a capacitor to store ignition coil energy prior to discharge, and to drive an ultra-high current channel across the gap when released. That powerful current creates an electromagnetic field that expands through the combustion chamber and ionizes the fuel air mixture, allowing the flame kernel to grow much more rapidly than in a conventional spark plug ignition event. The result is the most precise, powerful, consistent and complete burn possible.

Do you guarantee these performance benefits?

Yes, we do.  If you aren’t completely satisfied with your Pulstar spark plugs, return them, together with your dated sales receipt, to the merchant from whom you bought them within 30 days for a full refund of your purchase price.

Do Pulstar spark plugs come with a warranty?

Yes, they do.  If your Pulstar spark plugs prove to be defective in materials or workmanship within one (1) year of purchase, return them, along with your dated sales receipt and an explanation of the reason for the return, to Pulstar LLC, 2451 Alamo Avenue SE, Albuquerque, New Mexico 87106 and Pulstar LLC will replace them.

You can feel the difference

These plugs really walk the walk when you install them. I compared the spark compared to what I had in before and the size of the spark is huge! I had Iridium plugs in before they blew those plugs away! You can feel the difference in the throttle and the way it responds when you punch the gas. I would recommend them to anyone. YES they are pricy but I feel they are worth every penny. I would buy them again any day of the week!

I don't really write reviews… but I felt I had to with these plugs. I researched the website and technology and it made sense. I had no idea a spark plug could make such a difference in performance until now!! I have a 2014 EFI Triumph Bonneville - I have added a ton of performance upgrades and even remapped the fuel injection for more performance... All of the upgrades made a difference.. but none as dramatic - nor a bigger bang for the buck - as swapping out my plugs for these. I will put these plugs in anything and everything I have a spark plug in if possible. To me it's a just a no brainer. Do yourself a favor and get them.

IMMEDIATELY I noticed an improvement

I came across Pulstar spark plugs in some 4x4 enthusiast forums, and after looking through their website I was so impressed with all the background information provided (both the level of scientific analysis, and the sheer volume of empirical data) that I decided the generally high-price was justified, and I would try the plugs in my own vehicles (a 1989 Landcruiser and a 1997 4Runner). IMMEDIATELY I noticed an improvement in throttle response; it was particularly obvious in my 4Runner which suffered from an 'engine stutter' issue that I had been trying to properly diagnose and fix for about a year. Right away, the stutter issue went from being noticeable in approx 15-30% of certain throttle situations to scantily noticeable at all, and when it is noticed it's only in approx 0-5% of the same throttle situations. I also noticed a significant improvement in fuel economy. I am almost religious when it comes to calculating my overall fuel economy for the last tank of gas after every fillup (I even know exactly how much my different-than-factory-sized tires impact odometer readings on both of my trucks, based on distance comparisons between odometer vs. GPS data) and prior to changing the spark plugs I would average between 16-18 MPG (often in the high 16s - mid 17s, and only reaching 18+ on tanks that were nearly 100% highway miles at cruising speed) in the 4Runner. Now, since installing Pulstar spark plugs, I've filled-up 4x tanks of gas in the 4Runner (none yet in Landcruiser) - and on the first three (which were no different from my normal weekly commute to/from) I averaged 18+ MPG (up to 18.5) and on the last tank, which admittedly was quite favorable in that it was 260+ miles all on the highway at cruising speed (not more than 75mph) and coming from Bishop CA to Los Angeles CA (an overall drop in elevation of about 3,000ft) I averaged an ALL-TIME-HIGH overall 20.1 MPG!

Distinct improvement in fuel efficiency

The change to Pulstar® plugs gapped to factory 0.035″ was the only change made for this test. We waited for the first tank of fuel to burn through before making comparisons. At that point there were several distinct improvements: Better tip-in throttle response at any road speed and under heavy acceleration. Less throttle needed to sustain normal “cruise” road speeds. Less downshifting on grades with cruise control applied. Acceleration improved with both forced and cruise control downshifts. Distinct improvement in fuel efficiency; approximately one mile per gallon improvement (5.5%) under “city” and “highway” or interstate test conditions; this engine has always started well.  Click here to watch the video.

I have installed these in over 10 vehicles. Always made them run better and in most cases got better mileage. I installed a set in my 2006 GLI. Improved mileage by 2 mile per gallon. When I sold it, I took them out and mileage dropped immediately by 2 miles per gallon. I use these in all my cars and installed them in many of my friends cars and truck. Alos a huge improvement in the dual plugged Dodge trucks but you need to replace all the plugs.

Tractor spark plugs

Spark plug replacement is an easy and inexpensive way to keep your tractor operating at peak performance. Depending on how much work your tractor does, you may only need to replace the spark plugs once per season. Experts recommend new tractor spark plugs after every 100 hours of engine operation. Old spark plugs can suffer the effects of exposure to high temperatures. This results in debris build-up and wear and tear that inhibits an effective energy discharge. When you replace your tractor spark plugs, depend on Pulstar for the benefits of standard spark plugs, but with the added performance of innovative new technology.

I had no idea a spark plug could make such a difference in performance until now!! I have a 2014 EFI Triumph Bonneville - I have added a ton of performance upgrades and even remapped the fuel injection for more performance... All of the upgrades made a difference.. but none as dramatic - nor a bigger bang for the buck - as swapping out my plugs for these. I will put these plugs in anything and everything I have a spark plug in if possible. To me it's a just a no brainer. Do yourself a favor and get them.

Beyond happy

These are not your latest Fad of a spark plug, They work awesome as stated. After all these years of trying every spark plug brand out there. I now am beyond happy with these plugs since I can actually feel the consistent power from zero to my top end. Now the Pulstar's are going in my fleet! I cant wait to try them in my snow machine.

IMMEDIATELY I noticed an improvement

I came across Pulstar spark plugs in some 4x4 enthusiast forums, and after looking through their website I was so impressed with all the background information provided (both the level of scientific analysis, and the sheer volume of empirical data) that I decided the generally high-price was justified, and I would try the plugs in my own vehicles (a 1989 Landcruiser and a 1997 4Runner). IMMEDIATELY I noticed an improvement in throttle response; it was particularly obvious in my 4Runner which suffered from an 'engine stutter' issue that I had been trying to properly diagnose and fix for about a year. Right away, the stutter issue went from being noticeable in approx 15-30% of certain throttle situations to scantily noticeable at all, and when it is noticed it's only in approx 0-5% of the same throttle situations. I also noticed a significant improvement in fuel economy. I am almost religious when it comes to calculating my overall fuel economy for the last tank of gas after every fillup (I even know exactly how much my different-than-factory-sized tires impact odometer readings on both of my trucks, based on distance comparisons between odometer vs. GPS data) and prior to changing the spark plugs I would average between 16-18 MPG (often in the high 16s - mid 17s, and only reaching 18+ on tanks that were nearly 100% highway miles at cruising speed) in the 4Runner. Now, since installing Pulstar spark plugs, I've filled-up 4x tanks of gas in the 4Runner (none yet in Landcruiser) - and on the first three (which were no different from my normal weekly commute to/from) I averaged 18+ MPG (up to 18.5) and on the last tank, which admittedly was quite favorable in that it was 260+ miles all on the highway at cruising speed (not more than 75mph) and coming from Bishop CA to Los Angeles CA (an overall drop in elevation of about 3,000ft) I averaged an ALL-TIME-HIGH overall 20.1 MPG!

Best for small engines. Miraculous.

These plugs are miraculous in small engines on lawnmowers, etc. The difference between a regular plug and a Pulstar plug in a small engine is like night and day. Turned my kid's go-kart into a genuine death trap. Pressure washer turned into a beast. Lawnmower ignites before I'm halfway through the first pull.

Distinct improvement in fuel efficiency

The change to Pulstar® plugs gapped to factory 0.035″ was the only change made for this test. We waited for the first tank of fuel to burn through before making comparisons. At that point there were several distinct improvements: Better tip-in throttle response at any road speed and under heavy acceleration. Less throttle needed to sustain normal “cruise” road speeds. Less downshifting on grades with cruise control applied. Acceleration improved with both forced and cruise control downshifts. Distinct improvement in fuel efficiency; approximately one mile per gallon improvement (5.5%) under “city” and “highway” or interstate test conditions; this engine has always started well.  Click here to watch the video.

Frequently asked questions about snowblower spark plugs

How often should I replace my spark plugs?

For best results, you should replace your spark plugs every 50,000 miles under normal driving conditions.

How do I know if one of my spark plugs is fouled?

If your engine misfires, idles roughly or doesn’t run smoothly, one or more of your spark plugs may have become dirty or fouled.  Other symptoms of a fouled spark plug include a lack of acceleration, reduced gas mileage and difficulty starting.

Do I still need to gap spark plugs?

Pulstar spark plugs should be gapped to the setting recommended by the engine manufacturer up to 0.055” (1.40 mm).  Do not gap greater than 0.055”. For factory turbo or supercharged engines, gap Pulstar spark plugs to 0/025” (0.63 mm). 

What happens if I don’t gap the spark plugs correctly?

An engine with spark plugs that are not gapped correctly will not run smoothly and may not have power or misfire. 

How often should I replace my lawn mower spark plug?

Lawnmower spark plugs are typically replaced once a year.

Does it help to clean spark plugs?

Spark plugs cannot be cleaned enough to operate as new.  It is always best to replace fouled or contaminated spark plugs.

How do I install Pulstar spark plugs?

Pulstar spark plugs install the same way conventional spark plugs are installed.  When using a ratchet and socket or similar tool, care should be taken to not put a side load on the ceramic.

What kind of performance benefits can I expect when upgrading to Pulstar spark plugs?

Customers see significant improvements in engine torque, horsepower, fuel economy and emissions.  They notice quicker throttle response, smoother operation and improved towing capacity.

How do Pulstar spark plugs produce these performance benefits?

The science underlying our technology is sometimes called pulse power: energy accumulated over time is released quickly producing a very high power event, i.e., a pulse. Our patented technology applies this concept by embedding in Pulstar spark plugs a capacitor to store ignition coil energy prior to discharge, and to drive an ultra-high current channel across the gap when released. That powerful current creates an electromagnetic field that expands through the combustion chamber and ionizes the fuel air mixture, allowing the flame kernel to grow much more rapidly than in a conventional spark plug ignition event. The result is the most precise, powerful, consistent and complete burn possible.

Do you guarantee these performance benefits?

Yes, we do.  If you aren’t completely satisfied with your Pulstar spark plugs, return them, together with your dated sales receipt, to the merchant from whom you bought them within 30 days for a full refund of your purchase price.

Do Pulstar spark plugs come with a warranty?

Yes, they do.  If your Pulstar spark plugs prove to be defective in materials or workmanship within one (1) year of purchase, return them, along with your dated sales receipt and an explanation of the reason for the return, to Pulstar LLC, 2451 Alamo Avenue SE, Albuquerque, New Mexico 87106 and Pulstar LLC will replace them.

You can feel the difference

These plugs really walk the walk when you install them. I compared the spark compared to what I had in before and the size of the spark is huge! I had Iridium plugs in before they blew those plugs away! You can feel the difference in the throttle and the way it responds when you punch the gas. I would recommend them to anyone. YES they are pricy but I feel they are worth every penny. I would buy them again any day of the week!

FIND YOUR SPARK PLUG

Spark plug set

After you install a Pulstar spark plug set, you will understand why our spark plugs are known as the best you can buy. A set of spark plugs is installed in your engine, and changing them out is generally a simple task. When a spark plug set begins to wear out, your engine can misfire, stall and have trouble starting. If you have spark plug problems, you are in the right place.

SELECT YOUR MAKE AND MODEL

Pulstar invented the best spark plug set

spark plug set
What should you look for is a spark plug set? Timing. At the piston head, timing is everything. The right timing means more power and torque, quicker throttle response, better fuel economy, lower emissions and a more stable and long-lived engine. We knew that if we could improve the timing of combustion in our customers’ engines, they would be delighted by the results. That’s why we invented the Pulstar spark plug.

Frequently asked questions about our spark plug sets

How often should I replace my spark plugs?

For best results, you should replace your spark plugs every 50,000 miles under normal driving conditions.

How do I know if one of my spark plugs is fouled?

If your engine misfires, idles roughly or doesn’t run smoothly, one or more of your spark plugs may have become dirty or fouled.  Other symptoms of a fouled spark plug include a lack of acceleration, reduced gas mileage and difficulty starting.

Do I still need to gap spark plugs?

Pulstar spark plugs should be gapped to the setting recommended by the engine manufacturer up to 0.055” (1.40 mm).  Do not gap greater than 0.055”. For factory turbo or supercharged engines, gap Pulstar spark plugs to 0/025” (0.63 mm). 

What happens if I don’t gap the spark plugs correctly?

An engine with spark plugs that are not gapped correctly will not run smoothly and may not have power or misfire. 

How often should I replace my lawn mower spark plug?

Lawnmower spark plugs are typically replaced once a year.

Does it help to clean spark plugs?

Spark plugs cannot be cleaned enough to operate as new.  It is always best to replace fouled or contaminated spark plugs.

How do I install Pulstar spark plugs?

Pulstar spark plugs install the same way conventional spark plugs are installed.  When using a ratchet and socket or similar tool, care should be taken to not put a side load on the ceramic.

What kind of performance benefits can I expect when upgrading to Pulstar spark plugs?

Customers see significant improvements in engine torque, horsepower, fuel economy and emissions.  They notice quicker throttle response, smoother operation and improved towing capacity.

How do Pulstar spark plugs produce these performance benefits?

The science underlying our technology is sometimes called pulse power: energy accumulated over time is released quickly producing a very high power event, i.e., a pulse. Our patented technology applies this concept by embedding in Pulstar spark plugs a capacitor to store ignition coil energy prior to discharge, and to drive an ultra-high current channel across the gap when released. That powerful current creates an electromagnetic field that expands through the combustion chamber and ionizes the fuel air mixture, allowing the flame kernel to grow much more rapidly than in a conventional spark plug ignition event. The result is the most precise, powerful, consistent and complete burn possible.

Do you guarantee these performance benefits?

Yes, we do.  If you aren’t completely satisfied with your Pulstar spark plugs, return them, together with your dated sales receipt, to the merchant from whom you bought them within 30 days for a full refund of your purchase price.

Do Pulstar spark plugs come with a warranty?

Yes, they do.  If your Pulstar spark plugs prove to be defective in materials or workmanship within one (1) year of purchase, return them, along with your dated sales receipt and an explanation of the reason for the return, to Pulstar LLC, 2451 Alamo Avenue SE, Albuquerque, New Mexico 87106 and Pulstar LLC will replace them.

You can feel the difference

These plugs really walk the walk when you install them. I compared the spark compared to what I had in before and the size of the spark is huge! I had Iridium plugs in before they blew those plugs away! You can feel the difference in the throttle and the way it responds when you punch the gas. I would recommend them to anyone. YES they are pricy but I feel they are worth every penny. I would buy them again any day of the week!

It’s a no brainer

I don't really write reviews… but I felt I had to with these plugs. I researched the website and technology and it made sense. I had no idea a spark plug could make such a difference in performance until now!! I have a 2014 EFI Triumph Bonneville - I have added a ton of performance upgrades and even remapped the fuel injection for more performance... All of the upgrades made a difference.. but none as dramatic - nor a bigger bang for the buck - as swapping out my plugs for these. I will put these plugs in anything and everything I have a spark plug in if possible. To me it's a just a no brainer. Do yourself a favor and get them.

These are not your latest Fad of a spark plug, They work awesome as stated. After all these years of trying every spark plug brand out there. I now am beyond happy with these plugs since I can actually feel the consistent power from zero to my top end. Now the Pulstar's are going in my fleet! I cant wait to try them in my snow machine.

IMMEDIATELY I noticed an improvement

I came across Pulstar spark plugs in some 4x4 enthusiast forums, and after looking through their website I was so impressed with all the background information provided (both the level of scientific analysis, and the sheer volume of empirical data) that I decided the generally high-price was justified, and I would try the plugs in my own vehicles (a 1989 Landcruiser and a 1997 4Runner). IMMEDIATELY I noticed an improvement in throttle response; it was particularly obvious in my 4Runner which suffered from an 'engine stutter' issue that I had been trying to properly diagnose and fix for about a year. Right away, the stutter issue went from being noticeable in approx 15-30% of certain throttle situations to scantily noticeable at all, and when it is noticed it's only in approx 0-5% of the same throttle situations. I also noticed a significant improvement in fuel economy. I am almost religious when it comes to calculating my overall fuel economy for the last tank of gas after every fillup (I even know exactly how much my different-than-factory-sized tires impact odometer readings on both of my trucks, based on distance comparisons between odometer vs. GPS data) and prior to changing the spark plugs I would average between 16-18 MPG (often in the high 16s - mid 17s, and only reaching 18+ on tanks that were nearly 100% highway miles at cruising speed) in the 4Runner. Now, since installing Pulstar spark plugs, I've filled-up 4x tanks of gas in the 4Runner (none yet in Landcruiser) - and on the first three (which were no different from my normal weekly commute to/from) I averaged 18+ MPG (up to 18.5) and on the last tank, which admittedly was quite favorable in that it was 260+ miles all on the highway at cruising speed (not more than 75mph) and coming from Bishop CA to Los Angeles CA (an overall drop in elevation of about 3,000ft) I averaged an ALL-TIME-HIGH overall 20.1 MPG!

Best for small engines. Miraculous.

These plugs are miraculous in small engines on lawnmowers, etc. The difference between a regular plug and a Pulstar plug in a small engine is like night and day. Turned my kid's go-kart into a genuine death trap. Pressure washer turned into a beast. Lawnmower ignites before I'm halfway through the first pull.
The results are incredible.

Distinct improvement in fuel efficiency

The change to Pulstar® plugs gapped to factory 0.035″ was the only change made for this test. We waited for the first tank of fuel to burn through before making comparisons. At that point there were several distinct improvements: Better tip-in throttle response at any road speed and under heavy acceleration. Less throttle needed to sustain normal “cruise” road speeds. Less downshifting on grades with cruise control applied. Acceleration improved with both forced and cruise control downshifts. Distinct improvement in fuel efficiency; approximately one mile per gallon improvement (5.5%) under “city” and “highway” or interstate test conditions; this engine has always started well.  Click here to watch the video.

I use these on all my cars

I have installed these in over 10 vehicles. Always made them run better and in most cases got better mileage. I installed a set in my 2006 GLI. Improved mileage by 2 mile per gallon. When I sold it, I took them out and mileage dropped immediately by 2 miles per gallon. I use these in all my cars and installed them in many of my friends cars and truck. Alos a huge improvement in the dual plugged Dodge trucks but you need to replace all the plugs.

Engine spark plugs

After you install Pulstar spark plugs, you will understand why our spark plugs are known as the best engine spark plugs. Spark plugs are installed in your engine, and changing them out is generally a simple task. When spark plugs begin to wear out, your engine can misfire, stall and have trouble starting. If you have spark plug problems, you are in the right place.

Pulstar invented the superior engine spark plug

engine spark plugs
What does it take to be the best engine spark plug? Timing. At the piston head, timing is everything. The right timing means more power and torque, quicker throttle response, better fuel economy, lower emissions and a more stable and long-lived engine. We knew that if we could improve the timing of combustion in our customers’ engines, they would be delighted by the results. That’s why we invented the Pulstar engine spark plug.

Got these, installed them into my Jeep, and so far, it's been running smoother and more economical than before. Previously, I was getting ~15 miles per Gallon, now it's 20 MPG. Horsepower has increased, and the acceleration is faster than before.

It’s a no brainer

I don't really write reviews… but I felt I had to with these plugs. I researched the website and technology and it made sense. I had no idea a spark plug could make such a difference in performance until now!! I have a 2014 EFI Triumph Bonneville - I have added a ton of performance upgrades and even remapped the fuel injection for more performance... All of the upgrades made a difference.. but none as dramatic - nor a bigger bang for the buck - as swapping out my plugs for these. I will put these plugs in anything and everything I have a spark plug in if possible. To me it's a just a no brainer. Do yourself a favor and get them.

Beyond happy

These are not your latest Fad of a spark plug, They work awesome as stated. After all these years of trying every spark plug brand out there. I now am beyond happy with these plugs since I can actually feel the consistent power from zero to my top end. Now the Pulstar's are going in my fleet! I cant wait to try them in my snow machine.

IMMEDIATELY I noticed an improvement

I came across Pulstar spark plugs in some 4x4 enthusiast forums, and after looking through their website I was so impressed with all the background information provided (both the level of scientific analysis, and the sheer volume of empirical data) that I decided the generally high-price was justified, and I would try the plugs in my own vehicles (a 1989 Landcruiser and a 1997 4Runner). IMMEDIATELY I noticed an improvement in throttle response; it was particularly obvious in my 4Runner which suffered from an 'engine stutter' issue that I had been trying to properly diagnose and fix for about a year. Right away, the stutter issue went from being noticeable in approx 15-30% of certain throttle situations to scantily noticeable at all, and when it is noticed it's only in approx 0-5% of the same throttle situations. I also noticed a significant improvement in fuel economy. I am almost religious when it comes to calculating my overall fuel economy for the last tank of gas after every fillup (I even know exactly how much my different-than-factory-sized tires impact odometer readings on both of my trucks, based on distance comparisons between odometer vs. GPS data) and prior to changing the spark plugs I would average between 16-18 MPG (often in the high 16s - mid 17s, and only reaching 18+ on tanks that were nearly 100% highway miles at cruising speed) in the 4Runner. Now, since installing Pulstar spark plugs, I've filled-up 4x tanks of gas in the 4Runner (none yet in Landcruiser) - and on the first three (which were no different from my normal weekly commute to/from) I averaged 18+ MPG (up to 18.5) and on the last tank, which admittedly was quite favorable in that it was 260+ miles all on the highway at cruising speed (not more than 75mph) and coming from Bishop CA to Los Angeles CA (an overall drop in elevation of about 3,000ft) I averaged an ALL-TIME-HIGH overall 20.1 MPG!

These plugs are miraculous in small engines on lawnmowers, etc. The difference between a regular plug and a Pulstar plug in a small engine is like night and day. Turned my kid's go-kart into a genuine death trap. Pressure washer turned into a beast. Lawnmower ignites before I'm halfway through the first pull.

Distinct improvement in fuel efficiency

The change to Pulstar® plugs gapped to factory 0.035″ was the only change made for this test. We waited for the first tank of fuel to burn through before making comparisons. At that point there were several distinct improvements: Better tip-in throttle response at any road speed and under heavy acceleration. Less throttle needed to sustain normal “cruise” road speeds. Less downshifting on grades with cruise control applied. Acceleration improved with both forced and cruise control downshifts. Distinct improvement in fuel efficiency; approximately one mile per gallon improvement (5.5%) under “city” and “highway” or interstate test conditions; this engine has always started well.  Click here to watch the video.

Car spark plugs

Car enthusiasts are notorious for seeking out ways of getting more power from their machines, especially engine modification and customization. But rather than spending big money on big upgrades, upgrading your car spark plugs could be just the boost you needed. While vintage cars stand to reap the most benefit from improved car spark plugs, even the most sophisticated car will feel the difference. Pulstar pulse plugs can give you the extra power you’ve been looking for, and more.

SELECT YOUR MAKE AND MODEL

Boost power with Pulstar car spark plugs

Forget about fancy, expensive after-market exhaust systems, upgraded air filters, and carburation kits. For the price of a couple of Pulstar car spark plugs, you can get the most bang possible out of the combustion stroke of your car’s engine. Don’t be deceived by the look of Pulstar plugs– they look and install just like more conventional spark plugs. But when you look inside these plugs, you find a unique power-boosting technology at its core: a capacitator. This element stores energy, releasing it at the precise right moment.

Timing is everything, especially in a car engine. Our plugs give you a quicker throttle response, harder acceleration, and a smoother ride. What more could you ask for?

Enjoy longer car spark plug life with Pulstar plugs

The less time you spend maintaining your car, the more time you get to spend enjoying your drive, which is why longer spark plug life matters. Our car spark plugs deliver a more powerful burst of energy than our competitors– for a longer period of time. By combusting fuel efficiently and completely, our plugs stay cleaner and last longer.
Make sure you check your car spark plug wires when you upgrade your plugs. And crack in the plug wire insulation can cause low voltage in the ignition, causing a loss of overall performance. Black carbon built up on an old plug will tell you if you have a voltage problem or too rich a fuel mix.

Easier starts with Pulstar car spark plugs

A car that refuses to start is one of the most frustrating things car owners encounter. Car spark plugs can get fouled fairly easily from improper combustion, leading to difficult starting. But car spark plugs also just wear out often– so much so that in the old days, people carried a few spares around just in case. With ultra-efficient combustion, and the most powerful spark imaginable, Pulstar plugs help to make sure your car starts on the first try, every time.

SHOP NOW

Pulstar car spark plugs for better gas mileage and lower emissions

The better your fuel combustion, the more power your car engine will have. It also means you squeeze more power out of every last drop of fuel in your tank. Pulstar car spark plugs burn fuel more efficiently than conventional plugs– giving you more power, quicker throttle response, and improved fuel economy. Add in the bonus of producing lower emissions, and it’s hard to imagine why you would use any other spark plugs in your trusty steed.

Frequently asked questions about spark plugs

How often should I replace my spark plugs?

For best results, you should replace your spark plugs every 50,000 miles under normal driving conditions.

How do I know if one of my spark plugs is fouled?

If your engine misfires, idles roughly or doesn’t run smoothly, one or more of your spark plugs may have become dirty or fouled.  Other symptoms of a fouled spark plug include a lack of acceleration, reduced gas mileage and difficulty starting.

Do I still need to gap spark plugs?

Pulstar spark plugs should be gapped to the setting recommended by the engine manufacturer up to 0.055” (1.40 mm).  Do not gap greater than 0.055”. For factory turbo or supercharged engines, gap Pulstar spark plugs to 0/025” (0.63 mm). 

What happens if I don’t gap the spark plugs correctly?

An engine with spark plugs that are not gapped correctly will not run smoothly and may not have power or misfire. 

How often should I replace my lawn mower spark plug?

Lawnmower spark plugs are typically replaced once a year.

Does it help to clean spark plugs?

Spark plugs cannot be cleaned enough to operate as new.  It is always best to replace fouled or contaminated spark plugs.

How do I install Pulstar spark plugs?

Pulstar spark plugs install the same way conventional spark plugs are installed.  When using a ratchet and socket or similar tool, care should be taken to not put a side load on the ceramic.

What kind of performance benefits can I expect when upgrading to Pulstar spark plugs?

Customers see significant improvements in engine torque, horsepower, fuel economy and emissions.  They notice quicker throttle response, smoother operation and improved towing capacity.

How do Pulstar spark plugs produce these performance benefits?

The science underlying our technology is sometimes called pulse power: energy accumulated over time is released quickly producing a very high power event, i.e., a pulse. Our patented technology applies this concept by embedding in Pulstar spark plugs a capacitor to store ignition coil energy prior to discharge, and to drive an ultra-high current channel across the gap when released. That powerful current creates an electromagnetic field that expands through the combustion chamber and ionizes the fuel air mixture, allowing the flame kernel to grow much more rapidly than in a conventional spark plug ignition event. The result is the most precise, powerful, consistent and complete burn possible.

Do you guarantee these performance benefits?

Yes, we do.  If you aren’t completely satisfied with your Pulstar spark plugs, return them, together with your dated sales receipt, to the merchant from whom you bought them within 30 days for a full refund of your purchase price.

Do Pulstar spark plugs come with a warranty?

Yes, they do.  If your Pulstar spark plugs prove to be defective in materials or workmanship within one (1) year of purchase, return them, along with your dated sales receipt and an explanation of the reason for the return, to Pulstar LLC, 2451 Alamo Avenue SE, Albuquerque, New Mexico 87106 and Pulstar LLC will replace them.

You can feel the difference

These plugs really walk the walk when you install them. I compared the spark compared to what I had in before and the size of the spark is huge! I had Iridium plugs in before they blew those plugs away! You can feel the difference in the throttle and the way it responds when you punch the gas. I would recommend them to anyone. YES they are pricy but I feel they are worth every penny. I would buy them again any day of the week!

For the price of a couple of Pulstar motorcycle spark plugs, you can get the most bang possible out of the combustion stroke of your bike’s engine. Don’t be deceived by the look of Pulstar plugs– they look and install just like more conventional spark plugs. But when you look inside these plugs, you find a unique power-boosting technology at its core: a capacitator. This element stores energy, releasing it at the precise right moment.

Timing is everything, especially in a small engine. Our plugs give you a quicker throttle response, harder acceleration, and a smoother ride. What more could you ask for?

Enjoy longer motorcycle spark plug life with Pulstar plugs

The less time you spend maintaining your bike, the more time you get to spend out enjoying the ride, which is why longer spark plug life matters. Our motorcycle spark plugs deliver a more powerful burst of energy than our competitors– for a longer period of time. By combusting fuel efficiently and completely, our plugs stay cleaner and last longer.
Make sure you check your motorcycle spark plug wires when you upgrade your plugs. And crack in the plug wire insulation can cause low voltage in the ignition, causing a loss of overall performance. Black carbon built up on an old plug will tell you if you have a voltage problem or too rich a fuel mix.

I use these on all my cars

I have installed these in over 10 vehicles. Always made them run better and in most cases got better mileage. I installed a set in my 2006 GLI. Improved mileage by 2 mile per gallon. When I sold it, I took them out and mileage dropped immediately by 2 miles per gallon. I use these in all my cars and installed them in many of my friends cars and truck. Alos a huge improvement in the dual plugged Dodge trucks but you need to replace all the plugs.

Easier starts with Pulstar motorcycle spark plugs

A motorcycle that refuses to start on the first crank is one of the most frustrating things motorcycle owners encounter. Motorcycle spark plugs can get fouled fairly easily from improper combustion, leading to difficult starting. But motorcycle spark plugs also just wear out often– so much so that in the old days, almost every rider carried a few spares around just in case. With ultra-efficient combustion, and the most powerful spark imaginable, Pulstar plugs help to make sure your bike starts on the first crank, every time.

Pulstar motorcycle spark plugs for better gas mileage and lower emissions

The better your fuel combustion, the more power your motorcycle will have. It also means you squeeze more power out of every last drop of fuel in your tank. Pulstar motorcycle spark plugs burn fuel more efficiently than conventional plugs– giving you more power, quicker throttle response, and improved fuel economy. Add in the bonus of producing lower emissions, and it’s hard to imagine why you would use any other spark plugs in your trusty steed.

Frequently asked questions about spark plugs

How often should I replace my spark plugs?

For best results, you should replace your spark plugs every 50,000 miles under normal driving conditions.

How do I know if one of my spark plugs is fouled?

If your engine misfires, idles roughly or doesn’t run smoothly, one or more of your spark plugs may have become dirty or fouled.  Other symptoms of a fouled spark plug include a lack of acceleration, reduced gas mileage and difficulty starting.

Do I still need to gap spark plugs?

Pulstar spark plugs should be gapped to the setting recommended by the engine manufacturer up to 0.055” (1.40 mm).  Do not gap greater than 0.055”. For factory turbo or supercharged engines, gap Pulstar spark plugs to 0/025” (0.63 mm). 

What happens if I don’t gap the spark plugs correctly?

An engine with spark plugs that are not gapped correctly will not run smoothly and may not have power or misfire. 

How often should I replace my lawn mower spark plug?

Lawnmower spark plugs are typically replaced once a year.

Does it help to clean spark plugs?

Spark plugs cannot be cleaned enough to operate as new.  It is always best to replace fouled or contaminated spark plugs.

How do I install Pulstar spark plugs?

Pulstar spark plugs install the same way conventional spark plugs are installed.  When using a ratchet and socket or similar tool, care should be taken to not put a side load on the ceramic.

What kind of performance benefits can I expect when upgrading to Pulstar spark plugs?

Customers see significant improvements in engine torque, horsepower, fuel economy and emissions.  They notice quicker throttle response, smoother operation and improved towing capacity.

How do Pulstar spark plugs produce these performance benefits?

The science underlying our technology is sometimes called pulse power: energy accumulated over time is released quickly producing a very high power event, i.e., a pulse. Our patented technology applies this concept by embedding in Pulstar spark plugs a capacitor to store ignition coil energy prior to discharge, and to drive an ultra-high current channel across the gap when released. That powerful current creates an electromagnetic field that expands through the combustion chamber and ionizes the fuel air mixture, allowing the flame kernel to grow much more rapidly than in a conventional spark plug ignition event. The result is the most precise, powerful, consistent and complete burn possible.

Do you guarantee these performance benefits?

Yes, we do.  If you aren’t completely satisfied with your Pulstar spark plugs, return them, together with your dated sales receipt, to the merchant from whom you bought them within 30 days for a full refund of your purchase price.

Do Pulstar spark plugs come with a warranty?

Yes, they do.  If your Pulstar spark plugs prove to be defective in materials or workmanship within one (1) year of purchase, return them, along with your dated sales receipt and an explanation of the reason for the return, to Pulstar LLC, 2451 Alamo Avenue SE, Albuquerque, New Mexico 87106 and Pulstar LLC will replace them.

You can feel the difference

These plugs really walk the walk when you install them. I compared the spark compared to what I had in before and the size of the spark is huge! I had Iridium plugs in before they blew those plugs away! You can feel the difference in the throttle and the way it responds when you punch the gas. I would recommend them to anyone. YES they are pricy but I feel they are worth every penny. I would buy them again any day of the week!

Icing on the cake

They are the icing on the cake in a modified engine (excluding ignition mods). These plugs are especially good in an engine that doesn't have a centered in combustion chamber plug or dual plugged head.

Gas mileage went up about 10%

I put them in my '64 lancia flavia replacing very good champion n3 plugs. I set the car up for a fast idle at 1100rpm and after the plug swap the idle was 1400rpm and the mileage went up about 10%.

Running smoother

Got these, installed them into my Jeep, and so far, it's been running smoother and more economical than before.
Previously, I was getting ~15 miles per Gallon, now it's 20 MPG. Horsepower has increased, and the acceleration is faster than before.

It’s a no brainer

I don't really write reviews… but I felt I had to with these plugs. I researched the website and technology and it made sense. I had no idea a spark plug could make such a difference in performance until now!! I have a 2014 EFI Triumph Bonneville - I have added a ton of performance upgrades and even remapped the fuel injection for more performance... All of the upgrades made a difference.. but none as dramatic - nor a bigger bang for the buck - as swapping out my plugs for these. I will put these plugs in anything and everything I have a spark plug in if possible. To me it's a just a no brainer. Do yourself a favor and get them.

Beyond happy

These are not your latest Fad of a spark plug, They work awesome as stated. After all these years of trying every spark plug brand out there. I now am beyond happy with these plugs since I can actually feel the consistent power from zero to my top end. Now the Pulstar's are going in my fleet! I cant wait to try them in my snow machine.

IMMEDIATELY I noticed an improvement

I came across Pulstar spark plugs in some 4x4 enthusiast forums, and after looking through their website I was so impressed with all the background information provided (both the level of scientific analysis, and the sheer volume of empirical data) that I decided the generally high-price was justified, and I would try the plugs in my own vehicles (a 1989 Landcruiser and a 1997 4Runner). IMMEDIATELY I noticed an improvement in throttle response; it was particularly obvious in my 4Runner which suffered from an 'engine stutter' issue that I had been trying to properly diagnose and fix for about a year. Right away, the stutter issue went from being noticeable in approx 15-30% of certain throttle situations to scantily noticeable at all, and when it is noticed it's only in approx 0-5% of the same throttle situations. I also noticed a significant improvement in fuel economy. I am almost religious when it comes to calculating my overall fuel economy for the last tank of gas after every fillup (I even know exactly how much my different-than-factory-sized tires impact odometer readings on both of my trucks, based on distance comparisons between odometer vs. GPS data) and prior to changing the spark plugs I would average between 16-18 MPG (often in the high 16s - mid 17s, and only reaching 18+ on tanks that were nearly 100% highway miles at cruising speed) in the 4Runner. Now, since installing Pulstar spark plugs, I've filled-up 4x tanks of gas in the 4Runner (none yet in Landcruiser) - and on the first three (which were no different from my normal weekly commute to/from) I averaged 18+ MPG (up to 18.5) and on the last tank, which admittedly was quite favorable in that it was 260+ miles all on the highway at cruising speed (not more than 75mph) and coming from Bishop CA to Los Angeles CA (an overall drop in elevation of about 3,000ft) I averaged an ALL-TIME-HIGH overall 20.1 MPG!

Best for small engines. Miraculous.

These plugs are miraculous in small engines on lawnmowers, etc. The difference between a regular plug and a Pulstar plug in a small engine is like night and day. Turned my kid's go-kart into a genuine death trap. Pressure washer turned into a beast. Lawnmower ignites before I'm halfway through the first pull.
The results are incredible.

Distinct improvement in fuel efficiency

The change to Pulstar® plugs gapped to factory 0.035″ was the only change made for this test. We waited for the first tank of fuel to burn through before making comparisons. At that point there were several distinct improvements: Better tip-in throttle response at any road speed and under heavy acceleration. Less throttle needed to sustain normal “cruise” road speeds. Less downshifting on grades with cruise control applied. Acceleration improved with both forced and cruise control downshifts. Distinct improvement in fuel efficiency; approximately one mile per gallon improvement (5.5%) under “city” and “highway” or interstate test conditions; this engine has always started well.  Click here to watch the video.

I use these on all my cars

I have installed these in over 10 vehicles. Always made them run better and in most cases got better mileage. I installed a set in my 2006 GLI. Improved mileage by 2 mile per gallon. When I sold it, I took them out and mileage dropped immediately by 2 miles per gallon. I use these in all my cars and installed them in many of my friends cars and truck. Alos a huge improvement in the dual plugged Dodge trucks but you need to replace all the plugs.
