These G-power platinum spark plugs deliver the power and quality that you expect from NGK. The fine pure-platinum electrode tip remains virtually unchanged and reaches self-cleaning temperatures to deliver longer durability and optimum performance. Compared to conventional plugs, G-power plugs deliver better starts, superior acceleration and greater fuel economy. Trivalent metal plating provides superior anti-corrosion and anti-seizing properties. Corrugated ribs prevent flashover. Trapezoid cut ground electrode reduces quenching.
