The Official NHRA Spark Plug!
E3 Racing Spark Plugs are specifically designed for the extreme conditions that occur on the track, combining maximized spark and flame propagation for increased power and efficiency where needed most. E3 Racing Spark Plugs incorporate the Edge-to-Edge patented DiamondFIRE technology design that directly sends the spark travel towards the air-fuel mixture which maximizes the burn. The result is a faster flame kernel, a more complete combustion, greater power and higher fuel efficiency. These spark plugs produce excellent heat transfer, with added stability to the side wire in high compression engines. Ground electrodes reduce fuel consumption and improve hydrocarbon emissions in long-term use. E3's Racing Spark Plugs are the ideal plug for today's racer!
