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.
