03 ZTS cold air intake

My son purchased a cold air intake off of ebay for my wifes 03 ZTS. Just wondering if anyone had done this and if they know if it will void the warranty. I have a 50,000 miles left on the powertrain warrany and don't want to lose it over a couple of hp or mpg.

Legally, Ford can only void the powertrain warrenty if that part directly affects the failure, but the dealer will most certainly tell you otherwise. Check out sema.org for the full version of the law.
