The NGK G-Power platinum spark plug provides a cost-effective single-platinum upgrade for vehicles originally equipped with nickel plugs. A fine-wire platinum center electrode and trapezoidal ground cut reduce required voltage for better starts, improved acceleration and fuel economy. NGK's alumina silicate ceramic insulator and copper core help control temperatures, while trivalent plating and triple seals improve corrosion resistance and sealing.
