Racing Spark Plugs

For many years NGK Spark Plugs has been firing racing engines throughout the world. NGK Spark Plugs has become an icon in spark plug technology and we pride ourselves in offering racers a high quality product that will help rocket them to victory. We realize race teams push their vehicles to the edge. Knowing this we design every NGK Spark Plug to withstand severe mechanical and thermal shock associated with these high-revving, high-compression race engines. As a result of our superior quality, you’ll have confidence knowing you have the World Leader in spark plug technology firing your way to victory.

To withstand the severe conditions that occur in racing engines, NGK Racing Spark Plugs feature electrode materials and configurations as follows:

• Electrode materials– Many use precious metals such as platinum or gold/palladium for greater durability and lower voltage requirements.
• Electrode configurations– Fine-wire center electrodes provide better sparking and enhanced ignitability. Fine-wire ground electrodes further improve the ignitability of the plug.
• Insulator configurations– Special configurations are used for the insulator noses to improve throttle response.

NGK Spark Plugs can be found in every racing venue throughout the world. Whether you’re a weekend warrior or an accomplished racer NGK Spark Plugs is sparking winners.

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 inAustralasia. With NGK’s dedication to quality, outstanding reliability and state of the art manufacturing techniques, you can rely on your NGK Spark Plugs.

Dont 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.
