AOS - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

How critical is it to have a AOS? Also which set up is most ideal for a TC? Dual catch can, coolant warmed ones, seems like there are many variations to AOS's and a bit confused.

I'm approaching 5k boosted miles, and is worried something is gonna get clogged up if I don't get one soon. Thoughts?

I would do the pcv one with catch can. I personally don't like AOS because it drain crap back to the engine. Also, it affected my fuel trim quite a lot.

But isn't the purpose of an AOS to separate the crap out of the air and return it to the engine?

OP: I currently have a single catch can setup and am replacing it with a dual setup. I don't like the idea of splicing the pcv and breather lines together into one can so I ordered one can for the PCV side and the other for the breathers. Who knows if it's correct though
