Fitment Information: This Verus Engineering Air Oil Separator (AOS) is specifically designed for 2022 - 2025 Subaru WRX models. Features: The AOS keeps the intake system free from oil. Oil in the intake can lower octane levels, causing detonation, power loss, and carbon build - up. It comes with four 5 - micron coalescent filters (one on each inlet and outlet), baffling, and stainless mesh for outstanding 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: CNC machined from 6061 - T6 material. Red anodized for excellent corrosion resistance. Has a CNC laser - engraved logo. Equipped with Mil - Spec O - Ring Bosses. Four 5 - micron coalescent filters for top - notch oil separation. Prevents oil from entering the intake system. Baffles help separate oil particles better. Offers superior oil separation and is proudly made in the USA. What's Included: (1) Assembled AOS with 4 coalescent filters, internal baffling, and stainless mesh. A CNC bent bracket (for LHD only). 1/2' and 7/8' rubber hoses. All the necessary hardware for installation. Please note: Anodized parts may fade over time due to engine bay heat.
Using your Verus Air Oil Separator is easy. First, make sure you have all the parts included in the package: the assembled AOS, the bracket (if your vehicle is LHD), rubber hoses, and all the hardware. Follow the included installation instructions to mount the AOS to your 2022 - 2025 Subaru WRX. Once installed, it will start working immediately to keep oil out of the intake system. As for maintenance, check the coalescent filters regularly. If they seem dirty or clogged, you might need to replace them. You can also check the internal baffling and stainless mesh for any signs of wear or blockage. Regarding the anodized red finish, keep in mind that the engine bay heat can cause it to fade over time. This is normal and doesn't affect the performance of the AOS. If you decide to use the optional drain back kit or coolant add - on kit, follow the separate instructions provided with those parts. That's it! With proper use and maintenance, your Verus Air Oil Separator will serve you well for a long time.
