The NGK Standard spark plug provides OE-equivalent ignition reliability for routine maintenance and replacement. Packaged in NGK’s recognizable yellow box, it’s built to match original equipment performance and service intervals. A high-grade alumina silicate ceramic insulator boosts dielectric strength while a 98% copper core aids heat dissipation. Trivalent metal plating prevents corrosion and seizing, corrugated ribs reduce flashover, and triple seals guard against combustion leakage.
