Resolved 1990 Exhaust manifold stud thread pitch?

[eagelfan92]

Does anyone happen to know the OEM thread pitch of the manifold studs on a 1990 TSI. I bought some that are 1.25x45MM. I compared them to the studs on the car and they looked very similar but I just want to make sure.

That sounds about right, M8-1.25. That length seems like it'll do as well. Might need to be a few mm longer.

Thread pitch is 1.25.
