I know most say that its not really worth it but what will give the most HP and are there any for 03 A4 3.0L also do most of you still agree the best overall exhaust is still milltek thanks guys

 

Well it dosn't mater which one you by, an intake is an intake. the only difference from one to another is teh filter, cause one metal pipe is the same as another. CIA wont do anything diff unless you heat rap your headers not your intake(heat rap is an insulator it keeps heat in not out) otherwise teh air just warms up as it goes through the pipe. yeah...........
