Check your warranty and see what it says!
Mine says that if Ford installs aftermarket parts, they can still cover it under warranty, and the part has it's own warranty from its manufacturer. Also, they can't void your WHOLE warranty. It specifies that ford will not cover any items damaged due to a part put on after the car has left ford's control. Basically...they won't cover damage if you break anything...haven't heard of anyone breaking anything with a simple CAI install...
