NGK Standard spark plug is an OE-equivalent replacement designed for reliable starts and long service life. Built for original-equipment applications, it uses a robust alumina silicate ceramic insulator, triple-gasket sealing to prevent combustion leakage and a 98% pure copper core for effective heat transfer. Trivalent metal plating provides anti-corrosion and anti-seizing properties for easier installation and removal.
