I am working on swapping my 2013 coil packs to the 2015 style in hopes that the upgraded coil packs don't fail as often. I bought the Off the Line coil pack adapters to do that. I have some faith that this should help but I have come up with a way to make replacing them at the track easier just in case.
Once I break the bolt loose with a wrench I will be able to spin the extended bolt out by hand. I will add a tack weld to make sure the nut doesn't move.
