    NGK Racing Spark Plugs have been designed to withstand the rigours of racing applications. Tuned. racing-engines are often subjected to speeds in excess of 15.000rpm during races which means that temperature. pressure. vibrations and currents in the conbustion chamber are so extreme that conventional earth electrodes could break or melt.
