This is part of an S4 intake. Do you see the problem? It was more than 10 years ago when this was off last. I was recently trying to remove the rattling exhaust manifold heat sheild. I took this off and moved it over. I found that I had bent over the bottom part over while installing it and it never sealed correctly. I really hope that this solves the idle issue. I have a feeling that it just might. It will be a bit before I want to start this again, no exhaust currently.

Kind of funny how things work out.

 

yep, i'm sure it, and you, will be happier with that thing on correctly
