a 4hp gain is not gonna change your 0-60 or 1/4 mile times enough to justify not having the luxury of cold air ...
mine goes in and out because my a/c compressor (or clutch) is toast - but i hate it, just havent fixed it because thats $650 that i dont want to spend .... cant roll down my windows, because as some of you have seen, afro + driving w/ windows down = hair all on one side :lol:
