Default What size coupler and T clamp's

what size coupler (bellow) and T clamps will fit on the ls1 throttle body, mass air flow, and where the lid meets the maf? Thank you. I know the fernco is 3X3, but heard its a tight fit.

I'm not sure on the exact size on the OD of them, but the guys doing the Fernco mod throw them in the microwave to make them pliable so they fit (or boiling water).

Peace,
Craig.

I think the TB is 4" O.D. and the maf is 3.5" O.D., just pull them off and put a tape measure on it. Only takes 10 min to know for sure.
