The NGK Standard spark plug is a dependable OE-style replacement packaged in the familiar yellow box. It combines a pure alumina silicate ceramic insulator for dielectric strength with a 98% pure copper core for effective heat dissipation. Triple gasket sealing helps prevent combustion leakage and trivalent metal plating improves corrosion and seizing resistance. Corrugated ribs reduce flashover for consistent starting and idling performance.
