E3 Spark Plugs E3.36 Premium Powersport Spark Plug w/DiamondFIRE Technology (Pack of 1)

E3 Powersport spark plugs feature the patented DiamondFIRE ground electrode, which provides more power, faster starts, better fuel efficiency, and lower emissions in long-term use. The copper-core center electrode is encased in a 96% alumina ceramic insulator and secured to the steel shell. The DiamondFIRE ground electrode facilitate excellent heat transfer, and to create more turbulence in the cylinder. The 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.
