What is the name of the hose from the diverter valve to the intake?

[volfan98]

Hey guys, I picked up a A4 about a month ago and i've been lurking ever since. My car wasn't taken care of / modded very well and i'm trying to fix some of the things that the PO hacked. He's got an ebay blow-off valve on it and i'm trying to put a diverter valve back on. Does anyone know what the name of the return hose is called? I'm searching for it on ECS but I can't seem to find it.

Thanks!
Matt

My guess would be Recirculation hose? You might need to pick it up from a VW or Audi dealer.
