Description

The E3.68 Automotive Spark Plug is a 14mm, 1.000” reach plug with a gasket seat. It is designed to fit a wide variety of late model applications, especially Hemi applications. E3 automotive plugs feature three legs securing the DiamondFIRE electrode to the shell, which allows for excellent heat transfer and helps to create more turbulence in the cylinder. The patented DiamondFIRE side wire is proven to increase power, reduce fuel consumption, and improve hydrocarbon emissions in long-term use. The unique ground electrode and full-size center electrode are guaranteed for five years or 100,000 miles.
