hey another question guys...and again I have read post about this but just trying to make sure....with what I think, and am pretty sure with you guys help, the TB that came with explorer intake being a stock fox TB....I shouldnt have to do anything with that or the MAF, correct?....and it wont hurt performance or anything?...or down the road I read a post I should get a 65mm TB and a 70mm MAF?.... thanks again
