Fitment Information: This air oil separator is specifically designed for 2022 - 2025 Subaru WRX models. Features: The Verus Engineering Air Oil Separator (AOS) keeps the intake system oil - free. Oil in the intake can lower octane, cause detonation, reduce power, and lead to carbon build - up. It has four 5 - micron coalescent filters (one on each inlet and outlet), baffling, and stainless mesh for top - notch air filtration of crankcase air. Internal baffling inside the AOS further enhances filtration. With optional add - ons like the Verus AOS drain back kit and AOS coolant add - on kit, it can meet your specific needs easily. Key features include: CNC machined from 6061 - T6, black anodized for corrosion resistance, CNC laser - engraved logo, Mil - Spec O - Ring Bosses, four 5 - micron coalescent filters for excellent oil separation, prevention of oil entering the intake system, baffles for better oil particle separation, superior oil separation, and made in the USA. What's included: (1) Assembled AOS with 4 coalescent filters, internal baffling, and stainless mesh, CNC bent bracket (LHD only), 1/2' rubber hose, 7/8' rubber hose, and all hardware for installation. Please note: Anodized parts may fade over time due to engine bay heat.
Using the Verus Air Oil Separator is straightforward. First, ensure your car is a 2022 - 2025 Subaru WRX. Locate the appropriate place in the engine bay and use the provided hardware to install the assembled AOS. Connect the 1/2' and 7/8' rubber hoses as per the vehicle's specifications. You can also add the optional drain back kit or coolant add - on kit according to your needs. When it comes to maintenance, check the coalescent filters regularly. If they seem dirty or clogged, it's time to replace them. Also, keep an eye on the anodized parts. Due to the heat in the engine bay, they may fade over time, but this is normal and won't affect the separator's performance. If you notice any oil leakage or strange noises, stop using the vehicle and have it checked by a professional.
