I've got a massive GST donkey-kong barrel AOS on my WRX... if this does the same job, that's mighty impressive.

It is a blatant copy of the Prova A/O Separator with an extra input line added:

The extra line input makes it superior to the Prova in that it has inputs from both the crankcase and the valve covers. I personally would be skeptical that turning the oil filler tube into the equivalent of a catch can that drains back to the driver-side valve cover is equal to systems by Element Tuning, Crawford, and Pro-Vent, but maybe.
