The IAG Air/Oil Separator (AOS) is a smart move to protect and enhance your Subaru's performance. Developed over years of extensive testing on a range of standard and competitive applications, the IAG AOS offers unparalleled protection for your 2022+ WRX engine. Our exclusive AOS design incorporates a 1-liter cast aluminum swirl pot canister that significantly improves oil separation from the PCV system before returning PCV gasses to the intake. Crafted from a lightweight yet durable aluminum housing, the IAG AOS provides enhanced ventilation and features an innovative baffle design that sets it apart from the competition. This AOS works with all fuel types, prolongs the lifespan of your engine, improves crankcase ventilation and incorporates our innovative baffle design that sets it apart from competitors’ products. The IAG Air Oil Separator uses a unique baffle system to collect and drain the oil from your engine's PCV gasses back to the crankcase. The AOS body's inlet hoses create an internal gas vortex, which then filters through the baffles, trapping the oil and allowing the gas to escape from the top of the AOS canister. Because the OEM PCV remains functional, the engine is also able to provide additional vacuum, which helps to remove more of the PCV gasses. The IAG Air Oil Separator is equipped with a full set of custom-length SAE Quick Connection lines, making installation easier and reducing the risk of leaks with a more reliable and secure connection than standard hose clamps. Once installed, the IAG AOS system has the appearance of a factory component that seamlessly blends in with your Subaru’s engine.
