NGK Surface Gap spark plugs are specialty plugs that are nearly immune to pre-ignition, and usually require special high-energy ignition systems. They feature trivalent metal plating, corrugated ribs, pure alumina silicate ceramic insulators, copper cores, and triple seals. These plug characteristics provide superior anti-corrosion and anti-seizing properties, superior strength, and better heat transfer—as well as preventing flashover and leakage.
