PRODUCT DESCRIPTION

NGK Standard spark plugs are OE approved and recommended for reliable performance for most automotive and non-automotive applications. NGK Standard spark plugs feature a 5-Rib insulator design to prevent flashover and are also treated with corrosion-resistant plating to ensure ease of installation and removal. Cold rolled threads prevent damage to cylinder head. NGK's triple gasket sealing process virtually eliminates gas leakage past the shell. Solid Copper Core provides superior heat dissipation, conductivity and a broader heat range.
