The IAG Air/Oil Separator (AOS) is a worthwhile investment to safeguard and enhance the performance of your Subaru. Developed through years of testing on standard and competitive applications, the IAG Air/Oil Separator offers unparalleled protection for your 2006-2007 Impreza WRX or 2004-2007 STI engine. IAG 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. It is compatible with all fuel types, extends engine life, improves crankcase ventilation, and seamlessly integrates with standard ECU settings.
SAE QUICK CONNECTION LINES
IAG’s Air Oil Separator includes a full set of custom length SAE Quick Connection lines that simplify the installation of the AOS system, as well as reduce the chance of leakage because they offer a more reliable and secure connection than basic hose clamps. Once installed, IAG AOS system has a polished factory-like appearance that blends seamlessly with your Subaru’s engine.
