NGK nickel spark plugs feature a specially designed v-groove center electrode, improving ignitability and reducing quenching. The 98% pure copper core delivers increased heat dissipation for more reliable starts and reduced risk of overheating.

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 erformance, 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.

• Cold-rolled threads prevent cross-threading and damage to cylinder heads
• Trivalent plating eliminates need for anti-seize
• High-grade alumina silicate ceramic
• OEM quality construction nickel alloy center electrode provides consistent performance
• 98% Pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges
