The NGK Standard spark plug is an engineered OE-style replacement offering reliable everyday ignition. It uses a high-grade alumina silicate ceramic insulator and a 98% copper core for effective heat transfer and conductivity, plus triple gasket seals to prevent combustion gas leakage. Trivalent metal plating reduces corrosion and seizing for easier installation and removal, promoting consistent long-term service.
