E3.100 is a 14mm, 0.750 in. reach plug with a 13/16 in. hex, and a gasket seat. 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. This allows for excellent heat transfer and provides additional stability to the side wire in these high compression engines. The unique DiamondFIRE ground electrode is proven to increase power, reduce fuel consumption, and improve hydrocarbon emissions in long-term use. The E3 ground electrode and full-size center electrode also provides optimal performance over an extended product life.
