Oil entering from the crankcase vents spins counter clockwise through the entire body of the AOS, passing along four walls equaling roughly 50.25 sq\/in of surface area. The multiple baffle walls in our compact design simulate the surface area of an AOS that is 13.5\" tall! As oil accumulates on all the walls, gravity pulls it to the bottom of the can where it drains back to the engine block while water vapor and air merge with the intake air and are reburied in the engine.

Each engine vent port receives its own connection to the AOS. By giving each engine port its own entrance to the AOS we have allowed for more effective and faster excavation of crankcase pressure. Additionally, this reduces overall system pressure. With a 4\" OD and 5.75\" height, the AOS has an approximate 1 liter of holding capacity. The larger the AOS, the more power you can safely make without having to worry about the AOS overfilling.\u003cbr\u003e\u003cbr\u003eThe bottom of the AOS is shaped like a snail, redirecting positive crank pressure into the same swirl pattern produced by the 3 side ports. Allowing maximum oil drainage while separating oil from the air in all the venting ports.\u003cbr\u003e\u003cbr\u003eThe back plate of the AOS features a unique coolant routing system that heats the entire AOS to the same temperature of the engine. This maximizes the evaporation of any water collecting inside of the can. The hotter the AOS, the less water will collect inside and mix with the oil.\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"section--region\"\u003e\n\u003cdiv class=\"accordion--simple\"\u003e\n\u003ch4 class=\"accordion--simple__label\" id=\"why\"\u003eWHY?\u003c\/h4\u003e\n\u003cp class=\"accordion--simple__article\"\u003eThe COBB Subaru Air\/Oil Separator helps to prevent crankcase oil vapors from recirculating back through your engine's intake system.\u003cbr\u003e\u003cbr\u003eOil vapors passing through your engine's intake system lower the effective octane rating of fuel and can contribute to both oil and carbon buildup over time.\u003cbr\u003e\u003cbr\u003eNote: This AOS can be installed to 2002-2005 WRXs with modification to or relocation of the Cruise Control Module.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"section--region\"\u003e\n\u003cdiv class=\"accordion--simple\"\u003e\n\u003ch4 class=\"accordion--simple__label\" id=\"features\"\u003eFEATURES\u003c\/h4\u003e\n\u003cdiv class=\"accordion--simple__article\"\u003eSubaru Air\/Oil Separator WRX 2006-2007, STI 2004-2007\n\u003cul class=\"no-b-margin\"\u003e\n\u003cli\u003eCompact Cast Aluminum Tank Design\u003c\/li\u003e\n\u003cli\u003eBespoke COBB Anodizing on Caps\u003c\/li\u003e\n\u003cli\u003eWrinkle Black Powder Coated Canister\u003c\/li\u003e\n\u003cli\u003eLaser Etched COBB Logo\u003c\/li\u003e\n\u003cli\u003eDeveloped in Partnership with IAG Performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong style=\"color: #f06666;\"\u003eNOT LEGAL FOR SALE OR USE IN CALIFORNIA ON ANY EMISSION CONTROLLED MOTOR VEHICLE.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"ql-cursor\"\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003cspan class=\"ql-cursor\"\u003ePart #: 811615\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong style=\"color: #f06666;\"\u003eNOT LEGAL FOR SALE OR USE IN CALIFORNIA ON ANY EMISSION CONTROLLED MOTOR VEHICLE.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"COBB Tuning","offers":[{"title":"Default Title","offer_id":39542760865894,"sku":"cobb811615","price":565.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0075\/8703\/7237\/products\/cobb-06-07-wrx-04-07-sti-04-08-fxt-air-oil-separator-5379599.jpg?v=1770336369"},{"product_id":"precision-works-aos-air-oil-separator-subaru-wrx-02-07-sti-04-19","title":"Precision Works AOS Air Oil Separator - WRX 02-07 STi 04-19","description":"\u003cp\u003ePrecision Works AOS Air Oil Separator - Subaru WRX 02-07 STi 04-19\u003c\/p\u003e\n\u003cp\u003eAir oil separator removes oil from engine ventilation system so the oil does not get into the intake system.\u003c\/p\u003e\n\u003cp\u003eKey Features:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRetains OEM PCV valve\u003c\/li\u003e\n\u003cli\u003eEngine performs cleaner \u0026amp; efficiently \u003c\/li\u003e\n\u003cli\u003ePrecision CNC machined\u003c\/li\u003e\n\u003cli\u003e6061 billet aluminum\u003c\/li\u003e\n\u003cli\u003eHigh quality continental hose\u003c\/li\u003e\n\u003cli\u003eIncludes fittings, caps, and zip ties\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eDesigned to work with the following Subaru:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSubaru WRX 02-07\u003c\/li\u003e\n\u003cli\u003eSubaru STi 04-19\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Private Label MFG","offers":[{"title":"Red\/Black","offer_id":39570531844198,"sku":"PW-SUB-AOS-BLK","price":0.0,"currency_code":"USD","in_stock":true},{"title":"Red\/Silver","offer_id":39570531909734,"sku":"PW-SUB-AOS-SIL","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0075\/8703\/7237\/products\/precision-works-aos-air-oil-separator-wrx-02-07-sti-04-19-2729467.jpg?v=1770333624"},{"product_id":"verus-engineering-22-23-wrx-air-oil-separator-black-a0482a-blk","title":"Verus Engineering [22-26 WRX] Air Oil Separator | Black | A0482A-BLK","description":"\u003cp\u003eThe Verus Engineering Air Oil Separator (AOS) ensures the intake system remains oil-free.
