Show original supplier description
The IAG Air/Oil Separator (AOS) is a crucial component for safeguarding and enhancing the performance of your Subaru engine. Developed through extensive testing, this AOS provides robust protection for your 2015-2021 WRX engine. It features a 1-liter cast aluminum swirl pot canister designed to significantly improve oil separation from the PCV system before returning gases to the intake. Constructed from durable and lightweight aluminum, the AOS housing ensures improved ventilation. Its intelligent baffle system distinguishes it from competitors, promoting efficient oil separation. This system works with all fuel types, extends engine lifespan, enhances crankcase ventilation, and integrates seamlessly with standard ECU settings. Unlike traditional catch cans, the IAG AOS operates without the need for routine draining; separated oil gradually drains back into the engine's crankcase. The large canister capacity and proprietary heating system prevent sludge buildup and condensation, ensuring optimal performance and longevity. The system also includes pre-cut and crimped hoses on applicable Subaru models. It is available in black, red, or neon yellow to complement your engine bay. This AOS is compatible with 2015-2021 Subaru WRX and 2014-2018 Forester XT models.
