I have a 2012 gt premium. I am selling the jlt cold air kit and sct x3 tuner as combo, make offer. I am in baton rouge la. Has 3 unlocks left. I put the kit on for 3 weeks then pilot bearing in trans went out and gauge cluster died, so I returned it to stock...trading car in in may, so part s will never be used. About 1000 miles in cia and tuner has latest Bama tunes installed. I also have the stock gt mufflers and stock shifter for sale.
