Fitment Information: This Verus air oil separator is perfectly designed for 2022 - 2025 Subaru WRX models. Features: The Verus Engineering Air Oil Separator (AOS) keeps your intake system oil - free. Oil in the intake can lower octane levels, leading to detonation, power loss, and carbon build - up. It has four 5 - micron coalescent filters, one at each inlet and outlet, along with baffling and stainless mesh, providing top - notch air filtration for 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 requirements. Key features include: CNC machined from 6061 - T6, blue anodized for corrosion resistance, CNC laser - engraved logo, Mil - Spec O - Ring Bosses, four 5 - micron coalescent filters for excellent oil separation, preventing oil from 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 necessary hardware for installation. Please note that anodized parts may fade over time due to engine bay heat.
Using this Verus air oil separator is easy. First, gather all the parts included in the package. Install the assembled AOS using the provided hardware and rubber hoses. Make sure to connect everything properly to the Subaru WRX's engine. If you have the optional drain back kit or coolant add - on kit, you can install them according to the instructions that come with those kits. When it comes to maintenance, check the coalescent filters regularly. If they look dirty or clogged, it might be 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 won't affect the separator's performance. If you notice any oil leaks or other issues, stop using the separator and check for loose connections or damaged parts.
