DCPR8E Spark Plug NGK 4339

This high-quality standard spark plug is engineered to provide reliable ignition and consistent engine performance. It features a trivalent metal plating that provides superior anti-corrosion and anti-seizing properties for long-term durability.

• Corrugated ribs on the insulator prevent flashover to ensure a steady spark.
• Pure alumina silicate ceramic insulator provides superior strength and better heat transfer.
• Triple-seal process eliminates the possibility of combustion gas leakage.
• Copper core assists in heat removal to prevent pre-ignition and fouling.
