I talked to my dealer today and they said as long as I purchased the Mopar Cold Air intake, there would be no problem with the warranty. They also told me that it would add 15 HP to my 6 Spd Challenger. Sweeet ! I think as long as you service the car regularly with a Chrysler Dealer there should be no issues with Waranty voiding, that is what my salesman told me. Anyway just to be sure I am sticking with only Mopar add ons.
