NGK Racing Spark Plug

NGK spark plugs withstand the extreme conditions found in racing engines thanks to the following electrode materials and designs:

• Electrode materials - Many spark plugs feature precious metals such as platinum or a gold/palladium alloy to increase durability and reduce the required voltage.
• Electrode designs - Fine-wire center electrodes provide better sparks and improve ignition. Fine-wire ground electrodes enhance the spark plug's ignition capacity.
• Insulator designs - Special insulator designs are used to improve engine response.
