The NGK GP Platinum spark plug box of four offers a single-platinum upgrade for improved starts, fuel efficiency and durability over conventional nickel plugs. A fine-wire platinum center electrode and trapezoidal-cut ground electrode reduce required voltage and quenching, while the alumina silicate insulator and trivalent plating support strength and corrosion resistance. It provides a cost-effective performance-minded replacement for OE nickel plugs.
