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 into the atmosphere. The Competition Series AOS design is based on years of extensive testing on racing and high horsepower Subaru s. 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. The Competition Series AOS may require additional tuning calibration. Please consult a tuner for more information.
