Default air intake manifold
I'm looking at a F.A.S.T. air intake for the '04 vert. They list two models, one for a 78mm throttle body,and one for a 90mm. Anyone know is the size of the stock C5 LS1 throttle body? Any help is appreciated.

78mm. The 90mm is for the C6 LS2. You can run that one and see more gains, but you would have to get the 90mm LS2 throttle body to go with it.
