The NGK Standard spark plug is an OE-equivalent nickel replacement designed for reliable everyday ignition and long service life. It uses high-grade alumina silicate ceramic for superior insulation, a solid copper core for heat dissipation, and triple sealing to prevent combustion gas leakage. Trivalent metal plating resists corrosion and seizing for easier removal; corrugated ribs help prevent flashover for consistent engine starts.
