IAG V3 Street Series Air / Oil Separator (AOS) For 2015-21 Subaru WRX - Red Finish

The IAG Performance V3 Street Series Air/Oil Separator (AOS) is a valuable investment in maintaining optimal performance for your Subaru. The design of the Street Series AOS is the result of years of thorough testing on both standard and competition applications. This AOS consists of a 1-liter, cast aluminum swirl pot canister, which more effectively separates oil from the PCV system upstream of PCV gasses’ return to the intake system. The Street Series AOS has a heated aluminum housing, excellent venting, and it features a one-of-a-kind baffle design that stands out from the competition. The Street Series AOS works with all fuel types, prolongs engine life, enhances crankcase ventilation, and fits with standard ECU settings. The IAG AOS is engineered to require zero maintenance. Unlike standard catch-can systems, our Air Oil Separators do not require regular draining and maintenance. Oil that has been separated collects on the AOS can walls and slowly drains back into the engine's crankcase by gravity. The collected oil remains free of sludge with the help of our unique heating system, ensuring that there is no risk in reintroducing it into the engine. The large volume of the AOS body provides sufficient time for oil to drain back safely, eliminating the risk of overflowing seen in smaller catch cans.
