E3 Spark Plugs - E3.109
Spark Plug - Racing - 14 mm Thread - 0.708 in Reach - Gasket Seat - Non-Resistor - Each
Premium Racing Spark Plug; Non-Resistor; 5/8 in. Hex Size; 0.708 in. Thread Reach; 14mm Thread Diameter; Taper Seat; DiamondFIRE Tip w/Fixed Gap;
E3.109 is a 14mm, 0.708 in. reach plug with a 5/8 in. hex and a taper seat. It is built to have a cold heat range, non-resistor, and is used a variety of racing applications. 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 RPM 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.
- Patented DiamondFIRE Ground Electrode
- Edge-To-Edge Ground Electrode Out Performs Other Plug Designs
- E3 Equipped Engines Can Minimize Venting Of Unburned Fuel
- Burn Fuel More Efficiently By Burning Fuel More Completely
- Provide A Like-New Performance For The Life Of The Plug
- The Most Environmentally-Friendly Plug Available
