Audi TT mafs BT

[vwgtiking]

I am going big turbo and got the 80mm tt maf. My question is are all TT MAFS 80mm outside diameter?

I am looking at induction kits for Audi TT/s3 with heatshield to fit off the tt maf for my 1.8t a4.

I think it's just the 3.2l V6 engine isn't it, like what's fitted to the Mk4 R32?
