E3 spark plugs are said to accelerate the combustion process. However, modern EFI engines utilize extremely high compression ratios and very efficient combustion chamber designs that already yield a very fast burn rate.

Headquartered in Point Vedra, Florida, Pyrotek E3, d.b.a. E3 Spark Plugs, was formed to help customers increase power, improve fuel efficiency, and reduce engine emissions that contribute to global warming.

I highly recommend the E3 for small engines. I replaced the OEM plug we use on my Honda GX390 with the E3. I do not have a dyno to check hp, but it did make a noticable difference. It does not stall at idle anymore and the power seems to be as stronger, through the entire rpm range.

“I noticed a difference right away after installing these plugs in my truck. The plugs I took out had only 5000 miles on them so they were not worn. After installing the E3′s I noticed the idle smoothed out and the truck is running better. Gas mileage has went up 1 mpg.

5 years How often you change the spark plugs in your vehicle depends upon the type of plugs you use and how you drive the vehicle. Naturally, better plugs and easy driving conditions are optimal. E3 automotive spark plugs offer a 100K mile warranty, or 5 years from the date of purchase.

By simply replacing your existing plugs with premium E3 spark plugs, your ride will have the performance it deserves. Horsepower gains of 4-6% can be expected, depending on engine class size.

Tailored for high hp boosted (turbo, nitrous or supercharged) applications, the plug features E3's patented diamond-shaped ground electrode for maximum combustion and edge-to-edge spark, as well as a resistor to keep stock electronics functional. The E3.

However, in terms of practical performance, price, and usability for various applications, there is a huge difference between iridium spark plugs and every other spark plug category, with iridium spark plugs being the best component you can buy.

Iridium is a far stronger metal than platinum, capable of taking up to eight times as much wear and tear as a platinum spark plug before losing efficiency. This means that iridium spark plugs are less likely to fail than platinum spark plugs, need replacing less often, and perform better under tough conditions.
