The NGK Standard spark plug is a longstanding OE-style solution known for reliable starts and consistent operation. It pairs a high-grade alumina silicate ceramic insulator with a 98% pure copper core to improve heat transfer and conductivity. Triple gasket sealing prevents combustion leakage and trivalent metal plating guards against corrosion and seizing, making installation and removal easier while supporting longer service intervals and stable idling.
