If your engine bay changes, you can easily change how and where you mount the AOS. The center bracket allows for adjustable mounting. Multi-point Adjustable Mounting Bracket The hotter the AOS, the less water will collect inside and mix with the oil. This maximizes the evaporation of any water collecting inside of the can. The back plate of the AOS features a unique coolant routing system that heats the entire AOS to the same temperature of the engine. The oil vapor hose is designed to withstand oil and fuel vapors, exceeding SAE J30R7 standards. It will withstand coolant temperatures of +257☏. The supplied coolant hose is built to SAE 20R3 standards. The AOS drain port is able to be rotated for ease of installation.Īll fittings supplied with the AOS are anodized aluminum and feature Viton sealed ORB fittings. The unique snail design allows the system to breath without disturbing the swirl pattern. However, under heavy boost (especially on higher powered engines) the crank pressure will push back up the drain with the same air/oil mixture that is seen on the side ports. Under normal, off boost driving the weight of the collected oil will easily overcome the pressure in the drain line. The drain port is under the same crankcase pressure as the other ports that are on the side of the AOS.

Our AOS collects oil and actively drains the oil to the crankcase. Heavily modified race cars may be as often as every race. Why not use a catch can? Unmodified Subaru's may require catch can draining as often as every few weeks. Allowing maximum oil drainage while separating oil from the air in all the venting ports. 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.

No Maintenance or Manual Draining Required Unique Baffling Controls Crankcase Pressure There are NO plastic fittings that require thread tape to seal. The side of the AOS features 3 port billet hose barbs. Also available in World Rally Blue (automotive paint) Aluminum Body is powder coated in Red, Black, Gold, Dark Silver Every o-ring in our AOS is formed from Viton which offers superior temperature and chemical resistance. On the bottom, a thick Viton o-ring seals the can.

A total of 9 mounting holes give the breathing port a full 180° of rotation. The slower velocity leads to greater oil separation from the pressure stream. By increasing the overall volume of the breather opening on the top of the AOS, we have drastically decreased the exit velocity of the crankcase vent (CCV) stream.

Breather Port Rotation For Install EaseĪs air and particles of oil enter into the AOS, the largest particles of oil will collect on the inner surface of the can and drain to the bottom, but the smallest particles will remain suspended in the pressurized stream.Īs the air makes its way through the multi-stage baffle system, gravity pulls oil from the air.

The larger the AOS, the more power you can safely make without having to worry about the AOS overfilling. With a 4" OD and 5.75" height, the AOS has an approximate 1 liter of holding capacity. Additionally this reduces overall system pressure. By giving each engine port its own entrance to the AOS we have allowed for more effective and faster excavation of crankcase pressure.

Each engine vent port receives its own connection to the AOS. The Subaru EJ engine has 3 ports that vent crank pressure: one on each cylinder head and another on the top of the block. The Subaru FA engine has 2 ports that vent crank pressure: two at the top of the block. The AOS's approximate 1 liter capacity, fully heated housing, superior breathing and unique patent pending baffle design sets it apart from the rest. The design is based on years of service on racing and high horsepower Subarus. The IAG Performance Competition Series billet aluminum Air / Oil separator (AOS) vents crankcase vapors to the atmosphere.
