A few months back I bought a Crawford AOS v2 for GR / GV TMIC setup. I opened the box and connected the hoses to the AOS but never got around to installing it. As STU doesn't allow for PCV removal (required for install of this AOS), I've decided to go a slightly different route. The cheapest place I've found it online is $360; I'm asking $325 shipped, $300 local pick up (near RTP in North Carolina). This includes everything Crawford ships with it, never used.
This would work for a WRX as well, however the hose lengths on one or two hoses are slightly different (I believe).
