E3 Introduces the E3.112 DiamondFIRE Racing Spark Plug Designed for Chrysler Hemi and Ford Coyote Engines


Ponte Vedra, FL (October 31, 2017)…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 hp 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.

The E3.112 is the 13th SKU in the E3 racing spark plug line and continues the company’s aggressive push into the motorsports landscape. E3 racing spark plugs are designed specifically for normally aspirated and forced induction motorsports applications; drag, oval & off-road to allow maximum heat extraction, more horsepower, better torque and longer life.

“Whether it’s the Cobra Jet or Drag Pack Challenger, Detroit is churning out some fantastically fast cars these days,” says E3s vice president of motorsports, Rob Fisher. “Now they can get even faster. So many sportsman drag racers in sanctions like NHRA, NMRA, NMCA, etc. are racing these cars, we knew we had to develop a plug just for them. I can foresee that E3.112 will be one of our top sellers. After all, racers want to win and E3 will help them get there.”

Fisher adds, “E3.112 has been rigorously tested in the dyno cell and on the track with outstanding results. In its very first chassis dyno session the plugs showed a gain of 8hp and 14 lb./ft. torque over a leading competitor in the A-B Test.”

The test of the E3.112 was performed at Tuners Inc. in Jacksonville, FL on a 2014 Ford Mustang GT automatic with a 302 CID Coyote engine sporting forged internals and a Hellion Twin Turbo system running @ 16psi.
