NGK Standard spark plug is an OE-style replacement engineered for reliable ignition and extended life. It pairs a high-grade alumina silicate ceramic insulator with triple-gasket sealing to prevent combustion leakage and a 98% pure copper core for efficient heat dissipation and conductivity. Trivalent metal plating offers anti-corrosion and anti-seizing protection, and corrugated ribs reduce flashover for consistent performance.
