  • E3 Spark Plugs E3.72 Details

    18mm

    E3.72 is an 18mm, 0.430” reach plug with a taper seat. It primarily fits Ford applications from the 50's to 90’s. E3 automotive plugs have three legs securing the DiamondFIRE electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The patented DiamondFIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use. The unique ground electrode and full-size center electrode also provides optimal performance for a guaranteed five years or 100,000 miles.

    Increases Engine Power up-to 12% over Conventional Spark Plugs!

    E3 Spark Plugs utilize the latest in E3 technology, helping engines operate more efficiently, burn fuel more completely, reduces emissions and deliver maximum horsepower during every combustion cycle. When compared to conventional spark plugs, E3 Spark Plugs offer up-to a 12% increase in engine power and performance.
