Rated 5 out of 5 by No issues so far 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. October 13, 2016

Rated 5 out of 5 by 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. October 21, 2015
