NGK Racing Spark Plugs From professional racers with extremely modified engines to the weekend warrior, all levels of performance enthusiasts can rely on the advanced technology that’s built into all NGK racing spark plugs. They can be found in virtually every pit lane around the globe, and with a proven track record, they’re a winning solution with unbeatable reliability and performance. To withstand the harshest of conditions that occur in the most powerful, high compression racing engines, NGK racing spark plugs usually differ from normal spark plugs in both appearance and performance. They usually feature precious metal electrodes such as platinum or gold/palladium for greater durability and the lower voltage requirements means easier starting. Choosing a Racing Spark Plug: -Shell design To determine what kind of shell design fits in your engine, check the serial number of regulation plugs or the plugs you are currently using to verify the thread diameter, pitch, thread length and shell seat. -Firing End design Refer to the section below on electrode design to determine which type is best for your needs. -Heat range It’s important to choose a racing plug with a heat range that keeps the electrode at an optimum temperature under even the most torturous racing conditions. And remember: A higher heatrange number does not improve engine performance, it increases the plug’s ability to dissipate heat. -Resistors Due to advances in ignitionsystem technology, there is little if any difference in performance between plugs with resistors and those without. However, there are still some variations of some models that require plugs with resistors to avoid engine trouble.
