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.

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.

“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.

With decades of experience in spark plug engineering and the automotive aftermarket, the principals of E3 Spark Plugs realized that the key to producing a better spark plug did not lie in the use of fancy metals, such as iridium or platinum.

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.

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.

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 said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.

Comparison of best spark plugs for 2022

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.
