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 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 an 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.

WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
