    • 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
