I bought the E3 Spark Plugs for my Volvo XC70 because I was intrigued by the design. They fit perfectly and the engine worked normally after installation. My trip computer indicates a 0.5 mpg increase since installation which I did not anticipate.

Plugs only lasted a week. Engine had a spark detonation to it the whole time the plugs were in! Don't use these plugs

Installed new E3 plugs into my 2008 Sierra with 100000 miles, Gas mileage dropped from 420 miles to 300 miles a tank full ! Changed back to AC DELCO , mileage came back up.

Rated 5 out of 5 by P1PV Great plugs
Great looking spark plugs, appear to be one piece bodies unlike OEM three piece plugs. Preforming great so far with about 500 miles on them. Feels good to have the power back and about half the price of the OEM plugs.
