The IAG Air / Oil Separator (AOS) is a smart upgrade for your Subaru. Developed through years of testing on standard and competitive applications, the IAG Air / Oil Separator offers unparalleled protection for your 2002-2007 Impreza WRX, 2004-2007 STI or 2004-2008 Forester XT engine. Our 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. Constructed from a lightweight, yet durable aluminum housing, the IAG AOS offers improved ventilation and incorporates an intelligent baffle design that sets it apart from the competition. The IAG AOS works with all fuel types, improves crankcase ventilation, and seamlessly integrates with standard ECU settings. The IAG Air / Oil Separator was designed for ease of use and unlike ordinary catch-can systems, our Air / Oil Separators work without the need for routine draining or maintenance. The separated oil collects along the walls of the AOS can, then drains gradually into the engine's crankcase. The oversized AOS body allows the oil to drain slowly, eliminating the risk of overflow often seen in smaller catch cans. Our exclusive heating system ensures that the gathered oil remains free of sludge, reducing the possibility of reintroducing it back into the engine.
