It`s all in the name! Racing plugs are special spark plugs for racing and, thanks to their technical features, can also be used on the road. It only makes sense, however, when you are consistently at high RPM, as is the case in motorsport. Racing is not about the longevity of the plugs but rather how they withstand extreme vibration at higher RPM, extreme temperature cycles and prolonged use at full throttle. These features are a must-have for tuners and works teams both in motorcycles and go-karts. Not much can be said about the lifecycle of each plug as there are a number of variables in play, however in our experience 1-5 races is about right depending on category.
