    E3 spark plugs

    Any one use these? I searched "E3" and came up with nothing.

    Save your money and buy NGKs. It is a gimmick only and does not improve either performance or fuel economy.

      I put them in my Chevy Silverado. It was the first time I ever asked for a refund on plugs and, had I known how difficult it was going to be to get the company to honor their money back guarantee I would've never even considered them.

      Common sense has become so uncommon that I consider it a super power.

        I put them in my Focus last year. I gave them away in less than 1000 miles.

          I took them out of a Ford Ranger V6 and it ran better with OEM plugs. At a few dollars a piece it was a waste of money for sure.
