Product introduction
For racing and tuned engines
NGK racing plugs are special spark plugs for those who race or drive on circuits, or for those who increase engine output through tuning.
Choose the best racing plugs for your car and aim for the best performance.
Usage notes
Racing plugs are used to bring out the performance of an engine that has been tuned (modified to increase power), but the plugs do not actually increase power output.
Since these spark plugs are designed to meet the demanding conditions of tuned engines used in races and other such events, the heat value and firing part shape are selected (set) to suit the required conditions.
Please select racing plugs according to the degree of engine tuning and your desired driving conditions.
