The NGK Standard spark plug, packaged in a box of 4, is an OE-equivalent replacement delivering dependable ignition. High-grade alumina silicate ceramic insulator improves dielectric strength, and the 98% pure copper core aids heat removal and conductivity. Triple seals prevent combustion leakage while trivalent metal plating resists corrosion and seizing, simplifying both installation and future removal for routine maintenance.
