E3 Spark Plugs E3.104 Racing Spark Plug

E3.104 is a 14mm, 0.460” reach plug with a 5/8” hex and a taper seat. It is built to have a cold heat range, non-resistor, and is used a variety of racing applications. E3 racing plugs are fitted with its patented DiamondFIRE ground electrode, which is secured with two legs to the shell. This allows for excellent heat transfer, and provides additional stability to the side wire in these high RPM engines. The unique DiamondFIRE ground electrode is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use. The E3 ground electrode and full-size center electrode also provides optimal performance over an extended product life.

E3's DiamondFIRE edge to edge electrode provides maximum performance with increased efficiency, and a faster more complete burn Energy - More pressure is created against the cylinder and more of the available fuel is put to work Smoother Acceleration and Idle - The faster flame propagation initiated by the Patented DiamondFIRE ground electrode results in a more complete burn of the fuel/air mixture Quicker Starts - The patented Edge to Edge design concentrates spark energy resulting in easy starts in all conditions Primarily used in a wide variety of racing applications
