REVIEWS

E3.81 is a 12mm, 1.000” reach plug with a gasket seat. It fits a wide variety of late model applications, especially import. E3.81 has two 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.

e3.81 - Fire Power

Added the e3.81 to my AMG C63 and the power difference is instant!! These plugs were made for the car, looking forward to stocking up and or working with e3 on any new technologies.

Thanks
