I want to put a K & N Cold air intake on my tC... I know I can get the regular K and N filter, but I want the cold air cause is suppost to add 6 HP... Anyways, the last thing I want to do is void my warranty because there is a certain comfort feeling I get, knowing that if anything goes wrong until 36,000 miles, I dont have the worry about it... Anyways, will it void my warranty? Also, if I do end up going with the filter, I know TRD has a high performance filter... Is it the same as a K&N? Thanks
