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.
NGK iridium spark plugs currently represent the highest-quality technological solution. They feature an iridium-alloy on the middle electrode welded on in a special process using a laser. One of the world’s hardest metals, the precious metal iridium starts melting at a temperature of 2450°C and is therefore very resistant to spark erosion. By using it, the service life is doubled on average in comparison to standard nickel spark plugs.
