E3 Spark Plugs E3.48 Premium Automotive Spark Plug with DiamondFIRE Technology, Pack of 1 Spark Plug

The E3.48 auto spark plug is a high-performance 14 mm., 0.750" reach plug with a gasket seat designed to fit a wide variety of late model applications, particularly import vehicles. Featuring a unique design, it secures the patented DiamondFIRE electrode with three legs, allowing for excellent heat transfer and creating more turbulence within the cylinder for optimal combustion. This increases engine power, reduces fuel consumption, and improves hydrocarbon emissions over long-term use. With a fixed gap design, the spark plug boasts a DiamondFIRE open structure that forces air gap discharges, creating a superior edge-to-edge spark path. This enables the replenishment of the spark zone with a fresh fuel/air charge which improves combustion efficiency.
