Plunger Type Fuel Primer Pump Body Mikuni Keihin Sea Doo Yamaha Kawasaki

NGK Spark Plugs are designed to operate over a much wider heat range than ordinary plugs. They resist carbon buildup and pre-ignition. Each features high alumina ceramics for better heat transfer and electrical insulation. A patented triple gasket sealing process eliminates the possibility of combustion gas leakage, and a longer insulator nose prevents fouling and misfiring. A solid copper core and its nickel tipped electrode provide a longer plus life.

98% pure copper core increases heat dissipation for more reliable starts and prevents spark plug from overheating
High-grade alumina silicate ceramic insulator for superior strength and heat transfer
Cold-rolled threads to prevent cross-threading and damage to cylinder heads
Trivalent plating eliminates need for anti-seize and corrugated ribs prevent flashover
Quantity: 4 per package
