S197 Mustang CAI's and warranty

I posted this is the V-6 forum, figured I'd post it here since I own a GT.

I recently bought the ford racing pack one, a cai with tuner, muffers and an oil filter. I am under the pre-owned certified warranty. I was curious if my warranty would stay if I installed the cai myself, or if I had Ford install it would my warranty still be good. It took me several calls...fordracing.com, ford customer support, my salesman, and the parts AND service managers all did not know the answer.

Finally they got me in touch with the manager of used cars, because he had experinece with warranties particulars. He said that no matter who installs the cai, be it myself, the dealership, Henry Ford himself...the warranty would be voided for that part. He said that Ford would look for any reason to void a warranty. Now, if something went wrong in the car that was completely unrelated (his example was power windows) then the warranty would still cover. So basically the warranty is gone with the related parts.

So that said, Im still going to get it done. It seems relatively easy to install, I got the tuner and it looks pretty easy, and I never had the check engine light come on with my 94 gt that I was driving up to last month.

So be wary, warranty owners. Also of note is that my dealership, located about 20 miles northwest of Atlanta, wouldnt do the install. He said they wont touch cai's.

One thing Ive read on the internet is people installing their factory air intake if the check engine light did come on, then take it in. But cant Ford tell if the computer has been changed, even if I flashed it back to Stock?
