That's exactly it. The part number I posted earlier is what you need. You can find it on courtesy parts. Just put some hosing over the new part and it'll be fine.

I thought I read this somewhere but I'm not sure.;)

Haha yes! The Stillen instructions actually tell you to put one there and I believe provide one as well.

FWIW the reason I know is because I'm going through the same thing right now. I bought the car used from a dealer and it actually had the G3s on already. I had no idea about the AC issues and didn't know to check to make it was installed correctly until nothing but hot air.

Yeah I don't remember having extra pieces when I installed my intakes but its possible. I'm really surprised at how cheap that part is. Hopefully it won't be too ridiculous to install. Between myself and my roommate we've got a good amount of skill. Has anyone done one of these before?

Might be doing mine shortly depending on who gets to it maybe we can trade notes.

Here ya go.
