    I know air intakes have many threads. But had to take my 17 Tahoe to the dealership because there was hesitation and shifting problems. They drove it all day. And came to the conclusion that it was something with the transmission. There was a bulletin out on the transmission. About flushing it out twice to get the computer to relearn the shift patterns. Upon further review when they popped my hood they found out I had an after-market air intake system. I bought one about 8 months ago from SLP performance. It had been acting up I would say since I put the new system in. But I thought it was just a computer trying to learn. It has gotten worse as a months have gone by. So their conclusion is GM has a bulletin out that says it will void your warranty if you have an oil based air filter or any type of cold air intake. They are not to look at your vehicle unless the original equipment is in the vehicle. So just a heads up to everyone out there with air intake systems might check with your dealer to find out if it will void your warranty. My dealer has the bulletin from GM and I have it in my Tahoe. And it states in there that it will void your warranty.

    Interesting. Any way you can get a copy of the paperwork? You mentioned oil based filter. I have used k&n filters on my cars for years an never had a problem.

    I found several dealerships online selling after market intakes, exhaust, etc. many brands. So let them try denying me warranty.

    Yeah, an aftermarket intake system could void your warranty and the comments about GM offering a CAI are something I've also seen. Maybe it's a way to drive sales of their own systems? On another note... I'm wondering if there might be a valid concern about oil from the air filter contaminating the mass airflow sensor? This feels like a weak excuse but it could lead to driveability issues.

    basically if the dealer is going to be dick then just put your stock intake back on and take it to the dealer, when they are done put your intake back on, easy peasy
    my personal experience has been I took mine in with a CAI installed, they installed a new FACTORY engine and put my CAI back on and they never said a word about it other than I have a 3yr 100k warranty nationwide.
