Grimmspeed Air/Oil Separator

[Mikku]

Am looking for some feedback on these. I like the idea of the AOS and the Grimmspeed one seems to be the easiest to fit. By way of background, I recently picked up a 2005 JDM WRX Wagon, with 69K miles on the clock. It’s a standard car other than an STi Genome rear silencer. It’s just had the timing belt done but I’m thinking that an AOS would also be a good investment, even though I’ll be keeping the engine stock (famous last words). Has anyone here fitted one or had one of these? Thanks in advance for any replies.

A car I bought had a different brand fitted - It did not work, oil from the breather lines still found its way to the intake. I would invest in some catch tanks and set up a vent to atmosphere system, the tanks can be had relatively cheaply on their own from eBay etc

Thanks for the reply and suggestion. Can I ask what the other brand was?
