IAG Air / Oil Separator (AOS) For 08-14 Subaru WRX, 08-21 STI, 09-13 FXT, 05-09 LGT & OBXT
IAG AIR / OIL SEPARATOR (AOS) FOR 08-14 SUBARU WRX, 08-21 STI, 09-13 FXT, 05-09 LGT & OBXT { "__shgImageV2Elements": { "uuid": "s-00627073-5477-4ad4-9055-1da80438e592" } } SAFEGUARD YOUR SUBARU The IAG Performance Air / Oil Separator (AOS) is a smart upgrade for 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. The IAG AOS works with all fuel types, optimizes crankcase ventilation, and seamlessly integrates with standard ECU settings, so no tuning is required. KEEPS OIL OUT OF THE INTAKE The presence of oil within the engine's intake tract brings about a range of adverse effects, so preventing oil from entering the engine intake is crucial for avoiding premature mechanical issues and maintaining optimal performance. Initially, the oil coats the internal components of the intake, intercooler, and piping, which can potentially harm or prematurely deteriorate rubber or silicone hoses, eventually leading to compromised connections. Once the oil enters the intake tract, it has access to the intake manifold and then the engine’s combustion chamber. Oil inside the chamber has the potential to trigger detonation, pre-ignition, excessive emissions, smoke generation, power loss, reduced fuel efficiency, and in extreme cases, severe engine damage or even complete engine failure. { "__shgImageV2Elements": { "uuid": "s-9bbbfccb-ca86-46d6-8601-cf14e19318bf" } } { "__shgImageV2Elements": { "uuid": "s-0568c59e-becc-4e4d-9151-1cbcb5fcc76e" } } NO MAINTENANCE NEEDED The IAG AOS is designed for effortless upkeep. Unlike typical catch-can systems, our Air Oil Separators operate without the need for routine draining and maintenance. Separated oil gathers on AOS can walls and slowly drains into the engine's crankcase. With the help of our unique heating system, the collected oil remains free of sludge, ensuring that there is no risk of reintroducing it into the engine. The substantial size of the AOS body allows for a safe and gradual oil drainage process, effectively removing the chance of overflow commonly observed in smaller catch cans. HOW DOES THE AOS OPERATE? WHAT’S INSIDE? The IAG Air / Oil Separator features a unique baffle system that captures the oil suspended in your engine's PCV gasses, which are then able to drain back into the crankcase. The AOS body's inlet hoses are set up to create an internal gas vortex, which is then filtered through a series of baffles. The baffles gather the oil while enabling the gasses to exit from the upper part of the AOS canister. As the factory PCV remains active, this allows the engine to generate a vacuum in the AOS assembly to draw out even more of the PVC gasses. { "__shgImageV2Elements": { "uuid": "s-df1ec5f2-84a9-47a7-84a1-31716943e260" } } { "__shgImageV2Elements": { "uuid": "s-981f637c-bce5-4a82-8214-a5e48969ff80" } } IMPROVES UPON THE OEM PCV SYSTEM WITH NEW CHECK VALVE The AOS integrates with the OEM PCV system, while also providing a boost to its capacity. The AOS directs PCV gasses to the intake manifold, using an upgraded OEM style PCV valve for additional suction and air-oil separation. For applications using ethanol fuel, the AOS provides protection against problems like fuel dilution of the engine's lubrication system. MINIMIZES CONDEN…
