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.. 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.. NGK V-Power plugs feature a unique v-cut in the center electrode that directs the spark to the edge of the electrode, helping the spark develop more rapidly, increasing ignitability and reducing quenching.. TRIVALENT METAL PLATING: Delivers superior anti-corrosion and anti-seizing properties, ensuring ease of installation and removal. Pure alumina silicate ceramic insulator provides superior strength and better heat transfer. Trivalent metal plating for superior anti-corrosion and anti-seizing properties. 2014-11 VW Jetta, 2014-12 Beetle, Golf, Passat. NGK V-Power Spark Plug Box of 4 (ZFR6T-11G).
