The NGK Standard spark plug is an OE-quality nickel-alloy replacement built for reliable everyday ignition and long service life. It uses high-grade alumina silicate ceramic for a strong insulator, a solid 98% copper core for heat dissipation, and triple-gasket sealing to prevent combustion leakage. Trivalent metal plating resists corrosion and seizing for easier installation; corrugated ribs help prevent flashover for dependable starts.
