Subaru WRX STI Oil Catch Can - COBB - Air Oil Separator - `08-`20. Purpose-built vapor management for 2008-2014 WRX and 2008-2020 STI to help keep the intake clean and performance consistent.

COBB's AOS separates oil mist from crankcase gases before they re-enter the intake, helping reduce residue in the intercooler and intake tract. Designed for factory PCV function and model-specific fitment, it’s a practical upgrade for cars driven daily or hard on weekends, supporting reliability without added complexity.
