    • Perfect replacement, identical to factory
Compared it to the one that I pulled out they are absolutely identical to factory part. Extremely easy to install. In 5 minutes my misfire was gone. I figured it was the coil pack instead of the spark plugs because my friend took it out for me once before and found that one of the springs inside the coil pack was not maintaining its integrity with the spark plug. The misfiring got better once he straightened it out and after a period of time it got a lot worse so when I replaced the coil pack just now, misfires and rough idle are gone! AutoZone wanted a 120 to $160, save yourself a hundred bucks and buy this! ... show more

    • Great factory replacement part! Fixed my surging issues!
Bought this to replace the coil on my Chevy Cruze due to surging when accelerating and unstable idle conditions. Boots come pre coated with anti corrosion ointment and springs in the boots are nice and centered. Great factory replacement, just make sure the springs inside the boots are straight before installing! Fixed my surging and idle issues and saved me lots of money for mechanic diagnostics. ... show more

    • 2015 Chevy Sonic 1.4T
Vehicle was showing a misfire and I could see the spark jumping from the coil to the head. Replaced the coil pack and that solved the problem. I have read about enough vehicles with a similar condition to suggest that you replace the coil pack when changing the spark plugs as preventative maintenance. In this instance the coil pack failed at 10 years 125k miles. ... show more
