I don't understand why you need a 4.5" coupler for a 90mm throttle body? I have a 95mm tb and am using a 4" elbow. 90mm = 3.54" +~.5" for tb material = ~4" Just bring it up as it may make your search a little easier.

What tb do you have? This one is the edelbrock. And yes at the blade it is 90mm but the opening is stupid big. The stock tb will fit inside the edelbrock. I don't know why they made it this way. The 4" that's on there now won't stretch to fit at all. It fits inside it but not around it.

I guess Edelbrock is still holding on to the old powerstack philosophy with their throttle bodies. :dunno:

I did this dame thing on mine. But I used aluminum elbow with 4.5-4" straight adapter.

Alot of companies still taper them like that. Even the factory one is.


I went ahead and got the 4.5-4.5 from frozen boost.
