These coils will not fit the 2008-2014 5.7L Challenger. I have a 2012 Chalkenger RT and insisted on installing it, denying it was clearly fake. Of course the bolt broke because I stupidly did something wrong. The screws that are attached to the valve cover have been unscrewed a few millimeters. The cam pack should seat easily. After that, the installation was just a long way away. These overpriced, fancy red BS coils, heavily advertised as "plug and play" for the 5.7, led me to replace the valve covers. To make matters worse, I ended up ordering these $400 sniper valve caps which the youtube videos I saw said should fit crazy coils too. Guess what? The device has been deactivated again. So now my opinion is insanely overpriced junk with very poor manufacture or a design flaw. Don't waste your money trying to get cool red coils, go with the speed!
