Ok so I have been running a CAI intake since day 1 @ about 35miles total on the vehicle. I now have just under 300mi on the car and every once in a great while I hear like popping noise that sounds like it is comming right from the intake and feels/sounds like a very light backfire. Is anyone else experiencing this? When I say once in a while I mean it has probably happened a total of 5-10 times now. Should I be worried? I never really drove the car with the stock air box on so I don't know if it will do it with it installed and it happens so infrequently I know it will be hard for me or the dealer to replicate. What should I do?
