The outlet (side port) of the AOS-R is plumbed back to the turbo inlet pipe, creating a completely sealed system. The AOS-R mounts to the provided Radium Brake Master Cylinder Brace. The PCV valve is replaced by a custom machined straight-through adapter fitting, shown below.

In these cases, an ordinary small catch can may quickly fill with oil and not be adequate. Like the Radium Engineering Subaru Dual Catch Can Kit, the AOS-R (Air Oil Separator-Return) kit is responsible for keeping blow-by oil and other pollutants out of the intake pipe, manifold, turbocharger, and intercooler during all engine loads. The main difference is that an AOS-R system returns what is collected back into the oil pan so there is no servicing required. The built-in heater keeps water from condensing in the AOS-R. And because water is more dense than oil, there is an integrated water trap found around the bottom perimeter of the can. This prevents water from descending into the oil pan if ever present. Furthermore, because the water is trapped against the heater, it will eventually boil and evaporate out of the system.\u003c\/p\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":40944931536976,"sku":"RAD20-0258-00","price":474.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0058\/0252\/4785\/files\/20-0258-00updated.jpg?v=1728359150","url":"https:\/\/shop.redline360.com\/products\/radium-engineering-air-oil-separator-kit-subaru-wrx-2015-2021-forester-xt-2014-2018-20-0258-00","provider":"Redline360","version":"1.0","type":"link"}
