NGK Spark Plugs provide the ultimate performance for your engine. They're high quality, reliable and their advanced materials and design provide superior anti-fouling characteristics, which reduce carbon build up over a wide heat range. "V" Type plugs include a thin centre electrode tip, which is made of precious metal for added corrosion and oxidation resistance. The result: fast, sure starts and less misfiring, even in the coldest weather.
Ribbed to eliminate flash-over and improve performance.
Highest quality ceramic insulators improve heat dissipation and electrical insulation to provide long term durability.
More gaskets for peak performance.
Deep-seated copper core provides maximum engine efficiency at high and low speeds.
Projected insulator precision-engineered to prevent fouling and misfiring.
Nickel alloy tip prevents fouling, maximises performance and extends plug life.
