Spark Plugs E3.68 Premium Automotive Spark Plug W/Diamondfire Technology (Pack Of 1)

The E3.68 automotive spark plug is a high-performance solution designed to fit a wide range of late-model applications, particularly Hemi engines. With a 14mm thread diameter and 1.000-inch reach, this spark plug features a gasket seat and is widely available in automotive retail stores. E3s patented DiamondFIRE side wire is securely fastened to the shell using a three-leg design, which allows for excellent heat transfer and creates more turbulence in the combustion chamber. This innovative design results in a more complete fuel burn, leading to increased power, better fuel efficiency, and reduced hydrocarbon emissions during long-term use. Includes a unique ground electrode and full-size center electrode, offering optimal performance for up to five years or 100, 000 miles. The DiamondFIRE open design creates the preferred edge-to-edge spark path, replenishing the spark zone with fresh fuel/air charge and directly exposing the flame front to the piston head, resulting in improved engine power, reduced fuel consumption, and decreased carbon monoxide emissions. This spark plug design has been proven to extend the life of the spark plug while offering faster, smoother acceleration for a more efficient engine operation.
