and what do you base this opinion off of? What's the reason for the modification in the first place? To MOD his car!! I fail to see your reasoning on why you say if it's stock, then not "waste" his money on it Just a K&N filter will not yeild the same gains as an AEM CAI bud. Go with the AEM It isn't JUST for pretty looks
