Would anyone know what the mm dimensions are for the OEM throttle body? Looking to purchase a F.A.S.T. intake manifold. Was wondering if going up to an 80mm t.b. would be better over the OEM, but I have no idea what the OEM dimensions are... anyone???

 

the 90mm TB that FAST intakes are optioned with is a bit of overkill and will KILL your low end power unless you're pushing thousands of horsepower. the 78mm will do you just fine, FAST intakes have no such thing as an 80mm TB. Stock is 75mm.

 

alright, thanks for clearing that up for me.
