IAG Air Oil Separator AOS For 15-21 WRX, 14-18 FXT, Red

Part Number:IAG-ENG-7187RD
The IAG Air / Oil Separator (AOS) is a smart upgrade for your Subaru. Developed over years of rigorous testing on various standard and competitive applications, the IAG AOS provides unmatched protection for your 2015-2021 WRX and 2014-2018 Forester XT 2.0L FA 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. The durable and lightweight aluminum housing provides improved ventilation, while incorporating the use of an intelligent baffle design that sets it apart from the competition. The IAG AOS works with all fuel types, enhances crankcase ventilation, and seamlessly integrates with standard ECU settings. Unlike ordinary catch-can systems, the IAG Air / Oil Separator functions without the need for routine draining or maintenance. The separated oil gathers along the walls of the AOS canister, then drains gradually into the engine's crankcase. The large body of the IAG AOS eliminates the risk of overflow by allowing the oil to drain slowly, whereas smaller catch cans are unable to keep up and often require manual draining. The exclusive heating system on the IAG AOS ensures that the gathered oil remains free of sludge, reducing the possibility of reintroducing it back into the engine.
  • Keeps oil out of your intake for improved performance.
  • Unique baffle system that captures the oil suspended in your engine's PCV gasses, which are then able to drain back into the crankcase.
