Best spark plugs | Performance Spark Plugs

After you install Pulstar spark plugs, you will understand why our spark plugs are known as the best 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 best spark plugs

Best spark plugs
What does it take to be the best 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 spark plug.

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.

The best spark plugs

SHOP NOW

From the outside, our plugs look and install just like every other conventional spark plug. But embedded on the inside of Pulstar spark plugs is a novel piece of combustion technology, developed with the help of the Sandia National Laboratory. It delivers an ultra-high intensity, electrical discharge at the gap with more precise timing than any other product on the market. The result is the most rapid, powerful, consistent and complete burn possible.

The best spark plugs for engine performance

Spark plugs make a big difference in your engine performance. That’s why it’s important to make the right choice. Pulstar spark plugs improve your vehicle’s performance in ways conventional spark plugs can’t. That’s because Pulstar spark plugs use innovative plasma-assisted combustion technology–developed, built and extensively tested in the USA–to generate more horsepower, more torque and quicker throttle response. So whether your personal freedom machine is a high-performance motorcycle or just the family wagon, a simple spark plug upgrade makes your vehicle more powerful and quicker to respond. How do you know which spark plugs are right for your vehicle? Find out now.

Reducing emissions through better spark plug technology

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%.

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.

Improvement has been phenomenal

I have them in my 1970 jaguar E-Type and the performance improvement has been phenomenal including better gas mileage. I don't have but a couple of hundred miles on them but I sure like the additional performance they are giving me.

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.

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.
