NGK Standard spark plugs (in the iconic NGK 'yellow box' packaging) are a proven OE cornerstone and technology customers have relied on for decades. Engineered specifically for OE applications, NGK Standard spark plugs provide OE quality nickel alloy reliable performance and design. NGK's legendary high grade alumina silicate ceramic creates a stronger insulator for optimal dielectric performance, while triple gasket sealing prevents combustion gas leakage. Solid 98% pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges. Trivalent metal plating ensures superior anti-corrosion and anti-seizing properties.
Surface gap plugs are nearly immune to pre-ignition, and usually require a special high energy ignition system. They can be susceptible to fouling, especially in colder applications, but may be necessary in high compression applications.
NGK Standard spark plugs are proven technology that offer reliable performance. Actual OE or equivalent replacement spark plug. NGK Standard plugs are treated with corrosion-resistant plating to ensure ease of installation and removal.
