Re: Dealer approved mods
My dealership said gears and axle-back exhaust was perfectly fine, BUT you won't have those parts warrantied in your original or extended warranty.
What I was told by my dealership was that when they installed my gears, they were covered for 12 mos or 12,000 miles -- the greater of the two. If I had gotten them installed before taking possession of the car, it would've been 36 mos / 36,000 miles.
They will frown on a CAI and go ape sh*t over a tune. There is some debate as to whether disconnecting your battery and driving for 50 miles appropriately "erases the evidence" but that becomes a risk that you have to choose for yourself.
