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.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan\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.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003eThis part is legal for sale and use on Emissions Controlled Vehicles in all 50 states when used in accordance with the manufacturer's application guide because it has a California Air Resources Board (CARB) Executive Order (EO) number:\u003c\/p\u003e \u003cp\u003e\u003ca href=\"https:\/\/ww2.arb.ca.gov\/sites\/default\/files\/aftermarket\/devices\/eo\/d-660-25.pdf\" target=\"_blank\"\u003eD-660-25\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/ww2.arb.ca.gov\/sites\/default\/files\/aftermarket\/devices\/eo\/d-660-45.pdf\" target=\"_blank\"\u003eD-660-45\u003c\/a\u003e\u003c\/p\u003e \u003ch4\u003e\u003ca href=\"https:\/\/cobbtuning.atlassian.net\/wiki\/spaces\/PRS\/pages\/1435992251\/843615+-+Air+Oil+Separator+Subaru+WRX+2015-2020\"\u003eInstallation Instructions\u003c\/a\u003e\u003c\/h4\u003e","brand":"COBB Tuning","offers":[{"title":"Default Title","offer_id":50487245373726,"sku":"cobb843615","price":878.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0846\/6730\/2174\/files\/cobb-v3-air-oil-separator-aos-2015-2021-wrx-843615-974954.jpg?v=1767644120","url":"https:\/\/subistyle.ca\/products\/cobb-v2-air-oil-separator-aos-2015-2020-wrx","provider":"Subistyle","version":"1.0","type":"link"}
