I'm looking for some opinions on which is the most functional air oil separator on the market. Ease of install info would also be appreciated.

Thanks,
Owen

Also interested in this info.

Was looking at the Grimspeed AOS or the Hyperflow catch can/battery bracket

Which AOS is reputably better?

I have a Hyperflow and it works very well...MY06 STI

I just installed a hyperflow Catch can. I'll give it a week or so and report back.

i believe russ & burke are both ditching thier wanky aos oil caps for propper catchcans, seems they just don't work on the track

Crap dont say that. I wanna sell mine.

Works great! $110 for a S2 Industries one.

Hyperflow is the one to go for on Subaru. It actually has enough fittings for all the breather hoses.

do these wanky aos caps include the grimspeed ones?

i've got one and it's pretty decent, easiest install ever, can't comment on it's track performance though

I reckon they are good for daily duties but can't cope with the excessive amounts caused by laps.
I've chucked a catchcan between the AOS and inlet and it catches oil. It should be clean.

Guys, what are your opinions in regards to installing an AOS on a reasonably new car/daily? Just curious as I have been reading a lot of performance places in the states put them on as one of their first mods, but most people who use them here seem to be for race application only.
