Hey guys...was talking to someone today and they said that to run a Pro-M MAF on our cars we have to use a CAI...Is this true?...I want the Pro-M 75mm and was wanting it to go directly in place of my stock one, so that everything retains the stock look and you'd never be able to tell by looking at it. Was he right? I know he know's his stuff, but am just wondering if he was perhaps mistaken on this...Thanks
