Process West Ford Focus ST (Mk3)

Front mount intercoolers — direct-fit FMIC options for the Focus ST (Mk3), available in raw and black finishes.

Cold air intakes — enclosed intake kits listed separately for Mk3 and Mk3.5 models, so check the year and variant referenced in the title before ordering.

The third-generation Focus ST is commonly identified as the Mk3 (from 2012) and the facelifted Mk3.5 (from around 2015), both using the 2.0L EcoBoost turbocharged engine. Process West lists some items specifically for Mk3 or Mk3.5, as front bar, bonnet and engine bay packaging can differ between the two. Confirm your build date, variant and any existing aftermarket intercooler, piping or intake hardware already fitted, then match it against the fitment stated on the product page. If you are unsure which chassis variant you have, your VIN and compliance plate details will help confirm it.

Intercooler and intake fitment on the Focus ST generally involves removing sections of the front bar or undertray, relocating factory ducting and hoses, and reusing or replacing certain OEM fasteners and clips. Basic hand tools, trim removal tools and a safe way to raise and support the vehicle are typically required. Installation by a qualified professional workshop is recommended, and any changes to intake or boost pressure hardware should be assessed by a competent tuner where relevant. Always follow the instructions supplied with the product and check local vehicle regulations for road-use compliance.

Will a Mk3 intake fit a Mk3.5? Not necessarily — Process West lists Mk3 and Mk3.5 cold air intakes separately, so order the one matching your variant.

Is the intercooler a direct replacement? The Process West front mount intercooler for the Focus ST (Mk3) is designed as a bolt-in upgrade in the factory location; refer to the product page for what is included.

Do I need a tune? Retuning requirements depend on your overall setup — speak with your tuner about your specific combination.
