The NGK Standard spark plug offers dependable OE-style ignition performance with durable construction for routine service. It features a high-grade alumina silicate ceramic insulator, a 98% copper core to aid heat removal, and triple-gasket sealing to prevent combustion leakage. Trivalent metal plating provides corrosion and anti-seize protection for easier installation and removal, while corrugated ribs reduce flashover and support consistent ignition.
