The NGK Standard spark plug, packaged in a box of 10, provides an OE-quality replacement for routine maintenance. Its high-grade alumina silicate ceramic insulator improves dielectric performance and the 98% pure copper core aids heat dissipation. Triple gasket sealing prevents combustion gas leakage and trivalent metal plating reduces corrosion and seizing, making installation and removal easier while supporting longer service intervals.
