Cobb 13-18 Ford Focus ST Air Oil Separator

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.

Key Features

  • Billet 6061-T6 Aluminum Housing: Provides robust, corrosion-resistant structure that withstands high boost pressures and heat cycles.
  • Internal Baffling: Forces air-oil mixture through multiple passes to separate liquids effectively, collecting up to 90% more oil than stock.
  • Integrated Check Valve: Blocks drain-back of collected oil into the intake system during idle or low RPM conditions.
  • Complete Installation Kit: Includes -10AN fittings, stainless steel braid hose, custom bracket, clamps, and hardware for plug-and-play fit.
  • Made in USA: Precision CNC-machined for exact tolerances and direct compatibility with Focus ST PCV routing.

Product Notes

  • Requires periodic emptying of the collection canister to prevent overfill during track or high-boost use.
  • Compatible with stock or aftermarket intake systems; no ECU tuning needed.

Installation Notes

  • Professional installation recommended.
  • Bolts to factory valve cover mounting points using provided bracket 30-45 minute install time.
  • Reuses OEM PCV hose locations no cutting or permanent modifications required.
