Excellent performance, durability and value for money

Expertly constructed for durability, the NGK Nickel Spark Plug delivers optimum performance for longer. The trivalent metal plating provides superior anti-corrosion and anti-seizing properties, while corrugated ribs prevent flashover. It also features a pure alumina silicate ceramic insulator, providing superior strength and better heat transfer. The copper core aids in heat removal and the triple seals prevent leakage. For reliable durability and performance, you can count on the NGK Nickel Spark Plug.
