NGK have over 80 years of experience in spark plug manufacturing and are the world leader in spark plug technology. NGK has an extensive range of spark plugs, each with their own unique characteristics specifically engineered to its application and designed to suit a broad range of motorcycles, ATVs & UTVs in Australasia. With NGK's dedication to quality, outstanding reliability and state of the art manufacturing techniques, you can rely on your NGK Spark Plugs.
Don’t just ask for a spark plug, insist on NGK.
Spark plugs used for racing must withstand especially hard stresses. The speeds during a race are frequently in excess of 10,000 rpm. Temperature, pressure, and vibrations in the combustion chamber are so immense that conventional ground electrodes could break or melt. For this reason, racing spark plugs often come with specially designed ground electrodes, the most extreme form with a ring-shaped ground electrode. The spark jumps from the middle electrode to the ring-shaped ground electrode.
