I think its just generic but it's Greddy flanged. It's adjustable so like the others it probably holds 25+. I bought a box of parts that I really only wanted the intercooler out of and this was left over. The diaphragm and spring is solid, pushing on the bottom of the valve discharges air from the inlet on top.

I don't have the recirculation pipe, they go for like $10 or maybe its a common pipe thread, I'm not sure. I do have a Mitsu pipe with flange on it, there was someone in the mitsubishi forums selling a 1g BOV, if you want to pick that up I'll sell you this pipe & flange.
