E3.68
The E3.68 Automotive Spark Plug is engineered specifically for engines, making it an ideal performance upgrade for vehicle. Designed with E3’s patented DiamondFIRE electrode technology, this plug delivers a stronger, more complete spark for enhanced combustion efficiency.
The three-leg grounding design not only secures the DiamondFIRE electrode to the shell but also improves heat transfer and increases turbulence in the combustion chamber. The result is improved power, reduced fuel consumption, lower hydrocarbon emissions, and longer plug life.
With a 14mm thread diameter, 1.000" thread reach, and a gasket seat, the E3.68 is made for precise fitment and consistent performance. The 5/8" hex size allows easy installation, and the fixed gap design ensures reliable spark delivery without adjustment. Built with a resistor to suppress interference, the E3.68 is guaranteed to last 100,000 miles or 5 years.
