E3 Spark Plugs E3.80 Premium Automotive Spark Plug with DiamondFIRE Technology, 12mm, 1.000” Reach, Gasket Seat, Compatible with Late Model Import Applications, Pack of 1

The E3.80 auto spark plug is engineered for high performance in a wide range of late-model applications, particularly imports. Featuring a 12mm thread diameter, 1.000-inch reach, and gasket seat, this spark plug offers exceptional compatibility and reliable operation. Utilizes E3's patented DiamondFIRE technology, where two legs secure the DiamondFIRE electrode to the shell, ensuring superior heat transfer and helping to create additional turbulence within the cylinder for more efficient combustion. The DiamondFIRE side wire is scientifically proven to boost engine power, reduce fuel consumption, and lower hydrocarbon emissions over the long term. The spark plug's fixed gap design cannot be adjusted, but the DiamondFIRE open design allows air gap discharges, creating a preferred edge-to-edge spark path. This process replenishes the spark zone with a fresh fuel/air charge, resulting in improved combustion efficiency and more direct exposure of the flame front to the piston head. As a result, the E3.80 spark plug not only increases engine power output but also improves fuel efficiency, reduces gasoline consumption, and decreases carbon monoxide and hydrocarbon emissions. Ideal for both import and late-model vehicles, the E3.80 spark plug enhances engine performance.
