Improved Performance and Sound in a 50-State Legal Package
Your Focus ST's 2.0L EcoBoost is always hungry for more air, and our friends over at COBB Tuning have one of the best ways on the market to feed your ST's turbocharger and get an overall improvement in performance with their complete COBB Intake System. This kit replaces your Focus ST's stock air box, disposable paper filter, and inlet tubing with much more efficient hardware that improves turbo spool, throttle response, and overall performance all in one package. The COBB Focus ST cold air intake kit is even 50-state street legal, allowing you to get a nice start on a project build. The COBB intake features a relatively simple, bolt-on installation that makes it easy to get an improved sound and performance out of your 2.0L EcoBoost Focus ST.
100% Complete Intake Kit with Filter, Heat Shield, and Tubing
COBB carefully designed their 2.0L EcoBoost 2013 to 2018 Focus ST intake system to provide serious improvements over stock while not requiring a tune and staying 50-State street legal. The kit begins with a new dual-cone dry air filter that brings in more air than stock while offering more than adequate filtration. The filter is mounted in a full heat shield assembly that protects the filter from heat soak for improved efficiency. Each COBB intake kit comes with 3" mandrel-bent aluminum inlet tubing with a black wrinkle powder coat finish that shuttle air all the way over to your ST's turbocharger and reduce restrictions over stock. The kit also features a COBB sticker for the inlet tubing in your choice of color, which can be selected from our drop-down menu above. The kit comes with both hardware and instructions for installation.
