Guys:

I am working to put together a FAST 92, and a LS2 Throttle body setup for my 04 Z06.

The RED Silicon coupler that I have going into my stock LS6 Throttle (78mm) body has an Inner diameter of 4" (10cm).

Below is a picture of my RED 4" inner diameter coupler that I have mounted to my stock LS6 throttle body now.

Will this 4" silicon coupler work with a LS2 throttle body ? Or will I need a larger size coupler ?

Thanks !

4" is what I have on my LS3 TB, you should be fine.
