    15-20 WRX / 14-18 FXT V3 Competition Series Air/Oil Separator by IAG Performance

    The IAG Performance V3 Competition Series Air / Oil separator (AOS) is an excellent investment to keep your Subaru Competition Vehicle running well. The Competition Series AOS keeps oil out of the intake system of your engine by venting crankcase vapors to the atmosphere.

    The large, 1-liter, cast aluminum swirl pot canister collects the oil from the PCV system and allows it to drain away before the PCV gases are vented to the atmosphere, preventing all oil from reentering the intake tract. The AOS's fully-heated cast aluminum housing, superior venting, and unique, patent pending, baffle design set it apart from the rest. The Competition Series AOS is best suited for Drag Racing, Road Racing, and high horsepower Competition applications looking for superior crankcase ventilation. 

    Keeping oil out of the engine intake tract is extremely important towards preventing premature mechanical failure and maintaining performance. Oil in the intake tract of the engine has several detrimental effects. The V3 Competition AOS aims to prevent this from happening. As 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. As the air makes its way through the multi-stage baffle system, gravity pulls oil from the air. By increasing the diameter of the breather opening on the top of the AOS, we have drastically decreased the exit velocity of the crankcase vent (CCV) stream. The slower velocity leads to greater oil separation from the pressure stream. A total of 20 mounting holes enables the breathing port a full 360° of rotation. On the top, a thick Viton o-ring seals the can. Every o-ring in our AOS is formed from Viton which offers superior temperature and chemical resistance.

    The Subaru EJ engine has 3 ports that vent crank pressure: one on each cylinder head, and another on the top of the block. Each engine vent port receives its own connection to the AOS. By giving each engine port its own entrance to the AOS IAG has allowed for more effective and faster excavation of crankcase pressure. Additionally, this reduces overall system pressure. The AOS has an approximate 1 liter of holding capacity. The body of the IAG V3 AOS features an integrated coolant chamber that heats the entire AOS to the same temperature of the engine. This cast aluminum can holds more heat which maximizes the evaporation of any condensation collecting inside of the can. The hotter the AOS, the less condensation will collect inside and mix with the oil.

    The center bracket allows for adjustable mounting. If your engine bay changes, you can easily change how and where you mount the AOS. The V3 AOS body features a greater number of mounting holes enabling a wider range of adjustment. A single, laser-cut, mounting bracket is included that fits nearly all applications and configurations. A laser cut harness relocation bracket is also included.
