The NGK Standard spark plug (box of 4) provides OE-equivalent ignition reliability and long service life for routine replacements. A high-grade alumina silicate insulator improves dielectric performance while the 98% pure copper core aids heat removal and conductivity. Triple gasket seals prevent combustion leakage and trivalent metal plating reduces corrosion and seizing, making installation and removal easier.
