The IAG Performance Air/Oil Separator (AOS) is a valuable investment to protect and maintain peak performance in your Subaru. Developed through years of meticulous testing on standard and competitive applications, the design of the AOS offers unparalleled protection for your engine. This AOS features a 1-liter swirl pot canister made of cast aluminum. This construction significantly enhances the separation of oil from the PCV system before the PCV gasses are directed back to the intake system. The Air Oil Separator features an aluminum housing that has superior ventilation, and it incorporates an exclusive baffle design that sets it apart from the competition. It works with all fuel types, prolongs engine lifespan, optimizes crankcase ventilation, and seamlessly integrates with standard ECU settings, so no tuning is required. The AOS works with the OEM PCV system, while also providing a boost to its capacity. The AOS directs PCV gasses to the turbo inlet, using the factory PCV valve for additional suction and air-oil separation. For applications using ethanol fuel, the AOS provides protection against problems like oil dilution and lubrication issues. This is accomplished by capturing fuel vapors emitted from the oil and then reintroducing them into the intake tract for combustion. The AOS provides exceptional protection against oil entering the intake flow and oil dilution in the engine's lubrication system, exceeding the capabilities of the OEM PCV system alone.
- 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.
