2g maf coupler size

[overboosted1g]

OK so I now have a 2g maf and a custom bent 3in intake pipe. I was wondering if anyone knows what size coupler will fit the end of the 2g maf. And would it be OK to use a standard silicone non reinforced or rubber couplers for the intake off of the Turbo.

4 inches to 3 inches coupler is what you need

1g mas - 3 1/8 inches (3.125)
2g mas - 4 inches (4.0)
3g mas - 3 1/8 inches (3.125)

and it is fine to use a standard non reinforced, that side of the turbo does not see charged air.

Does a standard round 4 inch coupler fit the oval maf no problem?

yes, a 4 inch coupler will fit a 2g oval MAS
