The NGK Standard spark plug is an OE-equivalent replacement supplied in a box of 4 for routine service. It features a 98% pure copper core to aid heat dissipation and conductivity, a durable alumina silicate ceramic insulator for dielectric performance, and triple gasket seals to prevent combustion leakage. Trivalent plating improves anti-corrosion and anti-seize properties, while corrugated ribs reduce flashover risk for reliable operation.
