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.

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.

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.

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%.

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.

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!

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.

Noticed increase in horsepower

The spark plugs work great, and I have noticed a growth in horse power, and startup time. It is running better. Thank you for shipping quality products in a timely manner.
