Pulstar Introduces the World’s First Fine-Wire Iridium, High-Power Spark Plug

iridium spark plugs

Durable new line of spark plugs to harness plasma technology that delivers more power and torque, quicker throttle response, better fuel efficiency and reduced emissions. Pulstar LLC, a U.S.-based ignition technology company, today announced a new line of fine-wire iridium, high-power spark plugs for the automotive market – combining the industry’s most durable component materials with Pulstar’s unrivaled “Plasmacore” ignition technology.

FIND YOUR SPARK PLUG

The new line of fine-wire iridium spark plugs replaces Pulstar’s Inconel spark plugs and will be available for pre-order beginning Dec. 1, 2020. The price with the precious metal upgrade will remain $15.95 (U.S.).

“We are always looking for ways to impress our customers. The new product is the next generation of our patented, Plasmacore spark plug,” said Lou Camilli, president of Pulstar LLC. “Whether your automobile is a high-performance coupe, a pickup truck or the family minivan, a simple upgrade to the new line of Pulstar fine-wire iridium spark plugs will bring you an unparalleled driving experience. You’ll be able to feel the difference straightaway, and for years to come.”

The world’s first fine-wire iridium, high-power spark plug

The new Pulstar fine-wire iridium spark plugs feature innovations designed for high durability. Iridium, a hard, dense metal with an extremely high melting point, is an ideal material for resisting corrosion and arc erosion in today’s high-temperature engines. The fine-wire design produces a consistent and stable spark that refines the electrodynamics of the Plasmacore ignition event. The insulator has been rebuilt from the ground up, with a new, sturdier profile and a more robust ceramic build that increases tensile and dielectrical strength.

On the product’s design, Camilli, its inventor, added: “We tested the new line of Pulstar fine-wire iridium spark plugs and found that they have a 35% higher resistance to fracture, very low error rates, and cycle-to-cycle electrical discharge consistency that is the best we have ever seen. We think customers will love them.”

Liore Alroy, managing member of Passaic River Capital, a technology investment firm that recently acquired Pulstar LLC, said, “Lou and his team of engineers have responded to our challenge: extend the life of the Pulstar plug while improving on the benefits Pulstar customers have come to love – more power, more torque, quicker starts, smoother shifting, less fuel consumption and lower emissions. We could not be more pleased.”

Pulstar’s Camilli developed the Plasmacore ignition technology with Albuquerque’s Sandia National Laboratories, one of three National Nuclear Security Administration research and development (R&D) labs in the U.S. Their work led to the first transformational change to spark plug design in a century: a built-in capacitor that amplifies electrical discharge power at the gap and saturates the engine with a highly reactive field of ionized plasma.

Advantages of plasmacore ignition technology

Independent research has repeatedly confirmed the advantages of Plasmacore ignition technology. Studies at AVL – the world’s largest company for the development, simulation and testing of powertrain systems – Nissan and the University of Southern California have all observed dramatically faster ignition initiation and flame kernel development compared to conventional spark plugs.

FIND YOUR SPARK PLUG

Road and dyno testing of Pulstar spark plugs with Plasmacore technology have shown measurable improvements in horsepower, torque and mileage across a variety of vehicles. Tests conducted at Motiva Performance on a Lotus engine showed increases to horsepower of 7% and to torque of 10%. DSPORT Magazine reviewed Pulstar spark plugs and reported increased horsepower of 3.5% and torque of 3.8% on their Honda Civic.

Frequently asked questions about iridium 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.

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.

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.

Feels noticeably strong

The car feels snappier, more responsive to the throttle than before...it feels noticeably stronger and I’d be willing to bet it is stronger and probably in the vicinity of the 5-7 hp gain Pulstar documents were achieved in the Tahoe as well as a 2012 Charger.

I am extremely pleased with how these plugs work

I had a choice between good performance on short drives, or good performance on longer drives, and
always bad performance in cold weather. After I installed a set of Pulstar
plugs, I put the stock idle feed restrictors back in and leaned out the
idle. Now, throttle response from a cold start is flawless and throttle
response remains so even when the engine is fully warmed up. As soon as the
snow melted, I went for a 90-minute drive in 30-degree weather covering all
conditions from country roads to freeways to city streets without a single
stumble. I went for another long drive on a recent 65-degree day with
perfect performance again. On both drives I found I was more likely to hit
the rev limiter in first and second gears so power may be up as well. To
summarize, I thought the only way to solve the drivability problems was to
replace the carburetor with a fuel injection system, but just installing
the Pulstar plugs was enough. I am extremely pleased with how these plugs
work.

Super easy to install. ECM takes about 20 miles to “learn” even when battery disengaged during install. This morning drove around town. Performance so far about 40 miles is off the charts better than anything since car was new! 144,000 miles. Superb! All the superlatives one reads about are there. Very, very impressed! I had just replaced AC Delco plugs with Denso TT’s a month ago which was a large improvement over ACD plugs. Still, the idle ain’t right. That’s why I decided to try the Pulstar’s.

Better low end and shift control

Hard to separate out the products but I paired Pulstar plugs with Top Street Performance (TSP) coilpacks (45kV) on my 2014 V6 3.7l mustang and instantly stronger idle with better low end shift control. Typically my auto shifted into the 1.00 ratio 5th gear at 45mph and held it down to 41mph. With the Pulstar + TSP combination it still shifts at 45 but will hold it down to 39mph.

Likewise. when going uphill on the highway (65mph) it used to down shift from 6th gear (ratio 0.70) into 4th gear (ratio 1.23) at 55mph (mind you, uphill load). Now will hold sixth overdrive on the same middle TN hills down to 50mph. Lastly, are you sitting down, first 64mi (and the real reason I'm sending this comment) about 50:50 mix of city and highway = a clean 30mph. 64mi = 2.11 gal (monitored through OBD2 reader). I have to believe it is improving my low RPM torque.

I noticed right off the bat that the idle got smoother and seemed to be able to run quiet and slower. It didn't seem like the engine had to work as much for a very smooth idle. I had seen several YouTube videos from customers and independent sources that shown how much hotter the spark is and it's very noticeable the increase of spark.

I noticed my fuel mileage had increased a few miles per gallon and again the engine seemed to be able to accomplish the same tasks with less effort than before. Power is something else you notice. Besides the dyno charts you can find online, you can feel more as the power band is stronger.

I always thought the talk of in the past when people would talk up certain spark plugs just was always something you could sit back and laugh about as plugs never seemed to make any power changes. Well these plugs proved me wrong as without a doubt you can tell how much better the engine runs and feels stronger as well as you can 100% find tons of dyno results showing they indeed do. Again you can search YouTube for results by independent people.

Also since I have run my own tunes on two different engines, the spark charts can be pushed a little better as it seems to respond better. I am extremely satisfied with these plugs.  I had called with a question and I was given a great answer from a very knowledgeable person.

I have huge gains in the low end and no spark blowout in the top end

I have tested your spark plugs on our custom built Mazdaspeed 3 Generation 1 2008, I have custom R35 Hitachi Coils and paired them with your IEF1H 10 plugs and I can say, I have huge gains in the low end and no spark blowout in the top end, my car needed to be remapped to suit the bigger spark as I was getting more boost throughout the whole rev range.

Pulstar Spark Plugs Excel

I've just begun a second YouTube channel at https://youtube.com/@motorcycletechandtravel. I will be riding the 2000 Honda XR650R and '84 Honda XR350R extensively for videos. I need these bikes to perform well and start easily on camera. Pulstar spark plugs excel under these demands.

The Honda LOVES Pulstar spark plugs!

These Pulstar Plasma spark plugs are something else. Starting time is half of before. Throttle response is now razor-sharp, and I now have to keep my foot OUT of the throttle to avoid excess braking in traffic. Power is up considerably, and these helped MPG without any doubt.

I will definitely suggest your plugs to all

Thank you Lou for everything you have done. I have installed the new plugs in my dakota and it has ran amazingly! I'm not exactly sure what was going on with the misfire situation but it is running better than ever. I appreciate your time and assistance in this matter. I will be ordering more plugs soon and I will definitely suggest your plugs to all.

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.
