  • E3 Spark Plugs E3.52 Details

    14mm

    E3.52 is a 14mm, 0.375” reach plug with a gasket seat. It fits a wide variety of GM applications from the 50’s to early 80’s, and is generally the correct plug for older small block Chevrolet engines. 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. A patented Edge-to-Edge DiamondFire ground electrode design outperforms other plug designs by getting the combustion process started earlier in the combustion chamber. A faster, more complete burn provides optimum spark and an increase in engine life, fuel efficiency and money savings!

    DiamondFIRE Technology: E3 DiamondFIRE ground electrode technology works to create a plasma channel through which the spark current flows more easily. This helps the multiple-edge configuration to outperform all other spark plug designs available, including many premium offerings from the major manufacturers.

    Features:

    • Up-to a 12% Increase in Power over Conventional Spark Plugs
    • Faster Flame Kernel for Increased Fuel Efficiency
    • DiamondFIRE Technology
    • Open Ground Electrode Design
    • Forward Projection into Spark Zone

    Rated 5 out of 5 by from more than I expected ! Put a st of E-3 plugs in my 66 Gto. From the starting and driving it there was a very noticeable difference in performance ! Was more than I expected ! As far as mpg I don't know or care because it is not suppose to be economically fuel efficient the only difference is gas prices and they are so much higher than when I bought the car in 68 .
