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\u003e\u003cbr\u003e The 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\u003e\u003cbr\u003e The 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\/p\u003e\u003cp\u003eThe COBB Subaru Air\/Oil Separator helps to prevent crankcase oil vapors from recirculating back through your engine's intake system.\u003cbr\u003e\u003cbr\u003e Oil 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSubaru Air\/Oil Separator WRX 2015-2021\u003c\/p\u003e\u003cul\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         \u003cp\u003e \u003c\/p\u003e        \u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eFeel free to contact us at info@mlperformance.co.uk should you wish to double check!\u003c\/p\u003e        \u003cp\u003e \u003c\/p\u003e        \u003ch4\u003eCompatibility Check\u003c\/h4\u003e\u003cp\u003eTo ensure the part(s) you have ordered fits your vehicle, we run a compatibility check prior to dispatch.
