Racing Spark Plugs E3's unique DiamondFIRE ground electrode helps to create more turbulence in the cylinder, and facilitate a faster flame growth. The result is more complete combustion, which results in more power and better consistency. E3 Racing Plugs cover a wide variety of Motorsports applications.

It is built to have a very cold heat range, non-resistor, and is used typically in top fuel drag racing engines and similar applications. It crosses against AR5383. E3 racing plugs are fitted with its patented DiamondFIRE ground electrode, which is secured with two legs to the shell.

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.

E3 spark plugs have a unique ground electrode that encourages more turbulence in air/fuel mixture. This leads to a more complete burn of the available fuel and the downstream benefits of improvements in power, fuel efficiency, and reduced emissions."

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.

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.

E3 Spark Plugs Small Engine Plugs – For More Fuel Economy & Less Emissions. E3 Spark Plugs, with unique DiamondFire technology, deliver higher fuel economy, lower emissions and improve engine performance for all small engines including: blowers, weedeaters, generators, and lawn mowers.

Use the socket wrench to unscrew the spark plug by turning it counterclockwise. Once removed, check the electrode tip and ceramic insulator for build up or wear. Spray the dirty lawn mower spark plug with brake cleaner and let it soak for about ten minutes.

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.
