The Cobb Air Oil Separator mounts in the engine bay of 2013-2018 Ford Focus ST models to trap oil mist and vapors from the PCV system before they reach the intercooler and intake tract. This design maintains clean airflow for consistent power delivery and throttle response on the 2.0L EcoBoost engine. Built as a direct bolt-on solution with all components included for straightforward setup.
