The NGK Standard spark plug, sold in a box of 10, delivers OE-equivalent reliability for routine replacement. High-grade alumina silicate ceramic insulator provides strong dielectric performance and a 98% pure copper core aids heat dissipation and conductivity. Triple gasket sealing prevents combustion leakage and trivalent metal plating protects against corrosion and seizing, making the plug easier to install and remove over its service life.
