About E3 Spark Plugs E3.38 Premium Powersports Spark Plug

The E3.38 power sports and watercraft spark plug is a 10mm, 0.750” reach plug with a gasket seat. It is used in a variety of powersport applications, especially import motorcycles. E3.38 is often in used in Honda, Suzuki, Yamaha, and other high RPM engines. The patented DiamondFIRE ground electrode is secured to the shell with two legs to help facilitate heat transfer, and to withstand the intense vibration of powersport engine applications. The unique DiamondFIRE side wire 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. Part Number: E3.38; Resistor: Resistor; Hex Size: 5/8"; Thread Reach: 0.750"; Thread Diameter: 10mm; Seat: Gasket; Tip/Gap: DiamondFIRE Fixed Gap Cannot Be Adjusted. It replaces Champion G57C, G59C; and NGK CR7E, CR8E, CR9E. Our unique DiamondFIRE open design forces air gap discharges, creating the preferred edge-to-edge spark path. The design allows replenishment of the spark zone with a fresh fuel/air charge, and exposes the flame front more directly to the piston head than other plug designs. This distinctive spark plug design has proven to simultaneously increase engine power output, reduce gasoline consumption, decrease hydrocarbon and carbon monoxide emissions from the engine, and materially extend the life of the spark plug. Our lawn and garden spark plugs help engines operate more efficiently with a faster and smoother acceleration.
