98% pure copper core increases heat dissipation for more reliable starts and prevents spark plug from overheating
High-grade alumina silicate ceramic insulator for superior strength and heat transfer
Cold-rolled threads to prevent cross-threading and damage to cylinder heads
Trivalent plating eliminates need for anti-seize and corrugated ribs prevent flashover
Quantity: 1 per package
NGK Standard Spark Plug is manufactured to enhance the performance of the vehicle. It is constructed from durable material that is corrosion and abrasion resistant. The spark plug insulators are made of 99 percent pure alumina silicate, allowing for longer insulator noses for reduced fouling. This spark plug features a triple gasket sealing process that eliminates fuel leakage. It also includes a solid copper core that provides superior heat dissipation and conductivity. This spark plug has resistor that is produced with a glass and carbon mixture, which is fired to ensure superior performance and durability. It has corrugated ribs that prevent flashover and cold rolled threads to inhibit damage to the cylinder head.
