The NGK Standard spark plug, in a box of 10, is an OE-style nickel-alloy replacement offering reliable everyday performance. High-grade alumina silicate ceramic yields a stronger insulator for stable dielectric performance, and the 98% copper core aids heat transfer and conductivity. Triple gasket sealing prevents combustion leakage while trivalent plating reduces corrosion and seizing for easier installation and longer service intervals.
