Bought a K&N air charger cold air intake for my '06 goat. talked to 3 different dealerships, 1 said that it would definitely void the warranty, can only modify stuff from the catalytic converter/02 sensor back, the 2nd said he wasn't sure, thought it would void the warranty, the 3rd said i was ok to put it on, that it's up to the individual dealership about warranty crap. does anybody know for sure? i paid alot for the optional 6 year 100,000 mile warranty and am scared as hell to put it on. please help!
