I'm copywriting this idea lol
I didn't explain properly, if you have a look in the arch liner on the drivers side there is a vent. I want this vent for my Golf

You'll see what I mean. If you could cut 50mm round the louvres (to give me something to rivet it onto my arch liner)
I think the S3/TT has one in either arch (as they run twin intercoolers) so you could get one for yourself too
