Make More Power with E3 DiamondFIRE Race Spark Plugs

Since its founding in 2000, E3 has been on a mission to build a better spark plug. The result? E3’s advanced DiamondFIRE Racing Spark Plugs.

Inspired by the old racer’s trick of grinding spark plug electrodes to improve ignition, E3 DiamondFIRE plugs have a special ground electrode and full-size center electrode that create a more powerful and longer-lasting spark, ensuring the complete combustion of fuel in the cylinder. By reducing the amount of unburnt fuel leaving the cylinder, E3 DiamondFIRE Racing Spark Plugs increase power output while simultaneously reducing emissions.

E3 DiamondFIRE Racing Spark Plugs are covered by a five-year/100,000-mile limited warranty.
