The NGK Standard spark plug is a tried‑and‑true OE replacement engineered for durability and consistent ignition. Its alumina silicate ceramic insulator enhances strength and heat transfer, and a pure copper core assists rapid heat dissipation. Trivalent metal plating helps prevent corrosion and seizing while triple seals reduce combustion leakage, making these plugs a reliable option for routine engine maintenance in a box of ten.
