NGK Standard spark plug (box of 4) is an OE-equivalent nickel alloy replacement designed for reliable everyday operation. The alumina silicate ceramic insulator provides strong dielectric performance and the 98% pure copper core improves heat dissipation and conductivity. Trivalent metal plating resists corrosion and seizing, corrugated ribs prevent flashover, and triple gasket seals reduce combustion gas leakage for consistent performance.
