    Rated 1 out of 5 by from Can't be gapped, misfire in LSx engine I got a deal on E3 plugs and decided to try them on my 5.3 Silverado. I pulled the stock plugs out at 65k miles and installed the E3's and a set of MSD wires. The truck started and ran well.....for a week and a half. It started running rough and felt like it had misfires. Knowing the plugs and wires might be to blame I started pulling plugs. Three of them looked fouled. I had a buddy take me to the auto parts store where I bought NGK's. I checked the gap, lubed them with anti-seize, and installed them. The truck ran great again and the plugs were in the truck when I got rid of it years later.

    Rated 1 out of 5 by from Repeated misfires 2011 Buick Regal turbo. Just my opinion. I do not recommend. 1,400 miles on them, misfired like crazy. Changed out back to recommended factory brand. Very displeased....
