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.

The 98% pure copper core delivers increased heat dissipation for more reliable starts and reduced risk of overheating. While cold-rolled threads prevent cross-threading and damage to cylinder heads and a trivalent plating eliminates the need for anti-seize. Complete with a high-grade alumina silicate ceramic.

The principle of NGK's patented V-grooved spark plugs is technically simple but very effective. A V-groove is situated in the centre electrode. This forces the spark to occur at the outer edge of the centre electrode where it is easier to ignite the air-fuel mixture. In addition the voltage required to produce a spark is reduced. These two features give the benefit of improved ignitability especially in modern low-emission lean-burn engines even under extreme operating conditions.
