The machined aluminum separator holds 20.3 oz (600 mL), uses a coolant heated core to prevent water condensation, and has an integrated water trap. Sections screw together and seal with O-rings so the unit can be fully disassembled for service. The kit replaces the PCV valve with a straight-through adapter and includes the Radium brake master cylinder brace (20-0255) that serves as its mount.\u003c\/p\u003e\u003ch2 style=\"margin:16px 0 4px 0;\"\u003eSpecifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse;width:100%;margin-top:0;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eAir oil separator return (AOS-R) kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eCapacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e20.3 oz (600 mL)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e6.3 in tall (without fittings), 3.45 in diameter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003ePorts\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e10AN ORB inlet, outlet, and return; 4AN ORB coolant (x2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eMachined aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eIncludes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eAOS-R unit, mounting bracket, SAE J30R7 PCV hose, coolant hoses and fittings, PCV 10AN adapter, aluminum fittings and hose ends, stainless hardware, brake master cylinder brace (20-0255)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;\"\u003e20-0258-00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin-top:12px;\"\u003eDocuments: \u003ca href=\"https:\/\/www.radiumauto.com\/cdn\/shop\/files\/19-0136.pdf?v=1\"\u003eInstallation Instructions (PDF)\u003c\/a\u003e\u003c\/p\u003e\u003cp style=\"margin-top:12px;\"\u003eThis part fits:\u003c\/p\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" width=\"100\"\u003eYear\u003c\/th\u003e\n\u003cth align=\"left\" width=\"125\"\u003eMake\u003c\/th\u003e\n\u003cth align=\"left\" width=\"150\"\u003eModel\u003c\/th\u003e\n\u003cth align=\"left\" width=\"80\"\u003eSubmodel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2015-2017\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWRX\u003c\/td\u003e\n\u003ctd\u003eBase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2015-2017\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWRX\u003c\/td\u003e\n\u003ctd\u003eLimited\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2015-2017\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWRX\u003c\/td\u003e\n\u003ctd\u003ePremium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":47688413249708,"sku":"RAD20-0258-00","price":474.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0480\/2160\/2467\/files\/8075c884-06ad-46d7-8c28-19958ba9b4ef-800.jpg?v=1792715660","url":"https:\/\/onefastshop.com\/products\/radium-engineering-aos-r-air-oil-separator-kit-subaru-wrx-va-2015-2017","provider":"OneFastShop","version":"1.0","type":"link"}
