.38 Powersport Spark Plug

The E3.38 Powersport Spark Plug is engineered for high-performance applications, particularly in import motorcycles and other high RPM engines from manufacturers like Honda, Suzuki, and Yamaha. This plug features a 10mm thread diameter, a 0.750” thread reach, and a gasket seat, ensuring a secure fit. It is a resistor-type plug with a fixed DiamondFIRE gap that cannot be adjusted. The construction includes a patented DiamondFIRE ground electrode, which is attached to the shell with two legs. This design aids in heat transfer and provides superior durability against the intense vibrations inherent in powersport engine environments. The combination of the E3 ground electrode and a full-size center electrode contributes to optimal performance and an extended product lifespan. This plug replaces Champion G57C, G59C, and NGK CR7E, CR8E, and CR9E.
