E3 Spark Plugs, manufacturer of the new line of DiamondFIRE ignition products, introduces the E3.112 DiamondFIRE racing spark plug. Designed specifically for late model Ford Coyote and Chrysler Hemi engines, the new race plug has been under development by E3 for two years. Tailored for high-horsepower, boosted (turbo, nitrous or supercharged) applications, the plug features E3’s patented diamond-shaped ground electrode for maximum combustion and edge-to-edge spark, as well as a resistor to keep stock electronics functional. The E3.112 improves power for the 5.0L Ford Coyote and Chrysler Hemi muscle and race cars while reducing both fuel consumption and emissions. E3 racing spark plugs are designed specifically for normally aspirated and forced induction motorsports applications—drag, oval and off-road—to allow maximum heat extraction, more horsepower, better torque and longer life. The test of the E3.112 was performed at Tuners Inc. in Jacksonville, Florida, on a 2014 Ford Mustang GT automatic with a 302 CID Coyote engine sporting forged internals and a Hellion Twin Turbo system running @ 16psi.
