NGK Racing Spark Plug - R6252E-9

NGK Racing Series plugs are engineered to withstand the harshest engine conditions. Special insulator nose configurations improve throttle response. Corrugated ribs prevent flashover. Pure alumina silicate ceramic insulator, provides superior strength and better heat transfer. Copper core aids in heat removal. Triple seals prevent leakage.
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 combustion chamber are so extreme that conventional earth electrodes could break or melt.
