I have a 4.6l v8 and i plan on getting a new throttle body. I want 2 know what size i should get 70mm or 75mm, what would be the difference.

not too much.. if you plan on going forced induction then i wouldnt get anything else but 75mm. C&L show higer hp ratings with the plenium and the 75mm than the 70mm. ive got the combo (75mm accufab and c&L plenium) and i could really feel the pickup in throttle response. are you planning on getting a plenium as well? bc if not then you wont see very much difference at all

Get the 75 and be done with it.

Get a 75 mm T/B and plenum.There's no disadvantage to going with a bigger setup. www.rpmoutlet.com might even have free shipping.
