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.
