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.\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003eThe AOS-R is constructed of CNC machined sections that screw together and are sealed with O-rings. The AOS-R can be completely disassembled for cleaning or servicing.\u003c\/p\u003e\u003ch2 style=\"text-align:center;\"\u003eBENEFITS\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEffectively raises the fuel octane and increases engine performance with cleaner inlet air\u003c\/li\u003e\n\u003cli\u003ePrevents oil buildup in the intake or intercooler system walls, throttle body, intake manifold, etc.\u003c\/li\u003e\n\u003cli\u003eLowers hydrocarbon emissions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2 style=\"text-align:center;\"\u003ePORTS\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eInlet: 7\/8\"-14 threaded for 10AN ORB fittings\u003c\/li\u003e\n\u003cli\u003eOutlet: 7\/8\"-14 threaded for 10AN ORB fittings\u003c\/li\u003e\n\u003cli\u003eReturn: 7\/8\"-14 threaded for 10AN ORB fittings\u003c\/li\u003e\n\u003cli\u003eCoolant: 7\/16\"-20 threaded for 4AN ORB fittings (x2)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":48062391910618,"sku":"RAD20-0258-00","price":474.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/8623\/0234\/files\/ds_GPWQ_20-0258-00__83930.1725659263.1280.1280.jpg?v=1781530000","url":"https:\/\/www.iagperformance.com\/products\/radium-engineering-air-oil-separator-kit-for-2015-21-subaru-wrx-14-18-fxt-20-0258-00","provider":"IAG Performance","version":"1.0","type":"link"}
