I spoke w/two Subaru parts departments and it's 'discontinued/obsolete' from the factory.
Edit 6/4/2018: The WRX 46023FA000 part is still avl @ Partsouq.com.
EDIT 9/7/2016: I bought the JDM/EDM/Aussie WRX version - 46023FA000- as an extra from https://partsouq.com/ for $33.76 SHIPPED. They are in UAE, and it took less than 10 days to get it. It was factory packaged and labeled.
EDIT 11/20/2014: No longer available from Canada.
Per this from James614 (see page 2), this one from an EJ20G is likely the best option:

Stumbled across this guy. About $41, I calculated shipping to about $37 with Fedex or $12 DHL to Portland, OR.
James614 wrote:Just to be clear, the part in the rhdjapan link is the JDM 89-95 Legacy/WRX EJ20G inlet. It is slightly different than the USDM EJ22T part, specifically the fitting for the F-pipe is on the opposite side and the BPV fitting is at a significantly different angle, you will likely need custom hoses for both to make them fit (standard bulk hose works fine from my experience). All this is spelled out in the first link, but I don't want anyone seeing one for sale and jumping on it without being aware that it's not an exact fit.
EDIT 7/31/12: Per 'diesel devil' (page 2) they are still available IN CANADA and I just confirmed w/Richmond Subaru near Vancouver, BC they are in the Toronto warehouse @ $64.87 CAD + shipping, so 'diesel devil' is making y'all a good deal.
Same Part Number in Canada, too.
Get 'em while you can!
The US version:
I contacted two European LCBBS member and they can still get this P/N in Europe: 46023FA000
This is for the early '90's WRX and Legacy/Liberty from Europe, Australia, etc (the versions w/intercoolers). It is different, but similar:
I found it online in the UK Here: http://www.importcarparts.co.uk/parts.asp, but not cheap.
If you do the 'coffe cup' mod, some of the necessary connections can be integrated into the replacement piece. See this LINK for info.
Edit 2/2/12: I found these Cobb hoses for Evos. I'm sure the the end is too big, but someone may be able to make it work. They are about $95 each:
752001 Mitsubishi EVO X 2008 ; GSR & MR
Edit: 3/31/12 - Both items above are no longer listed....may be disco'd @ Cobb, too!
I have my own collection of broken/cracked/torn ones :
