Was just at my dealer today and tried to wheel and deal a price on the CAI and the guy was a DICK about it. The dealer sent me a 15% off any part thanking me for the purchase of the car so when I tried to use it the parts guy upped the cost of the CAI saying that he couldnt sell it cheaper.
I laughed and told him I can get it for $110 all day long online and he tried to tell me it was a fake until I showed him the web site then he shut his mouth.
Any way he said that its BS that the dealer has to instal to maintain warranty and if its put on correctly then that is all that matters. Besides if not on correctly the car wouldnt run for crap and you should be able to tell.
I am going to instal myself as well and just take the bumper off using the injens instal directions.
There was another kid at the dealer with the same MS3 and had a CAI and he took me for a ride and it was a noticable difference over my stock MS3.
I am sold and so should be anyone else with a MS3.
