NGK Standard spark plug (box of 10) is an OE-quality replacement offering steady ignition and dependable life. The alumina silicate ceramic insulator improves dielectric strength while the 98% pure copper core helps dissipate heat and maintain conductivity. Trivalent metal plating reduces corrosion and seizing for easier installation, corrugated ribs limit flashover, and triple gasket sealing prevents combustion gas leakage for reliable operation.
