The NGK Standard spark plug is a proven OE-quality replacement offered in the brand’s iconic yellow box. Constructed with nickel-alloy components and a high-grade alumina silicate ceramic insulator, it provides reliable ignitability and dielectric strength. A 98% pure copper core aids heat dissipation and conductivity, triple gasket sealing prevents combustion leakage, and trivalent metal plating reduces corrosion and seizing for easier installation and removal.
