Process West Cold Air Intake – Ford Focus ST Mk3.5 (2015–2018)

The Process West Cold Air Intake is a proven performance upgrade for the Ford Focus ST Mk3.5 (2015–2018), designed to overcome the factory airbox's restrictive design. While the OEM setup focuses on sound suppression, it introduces unwanted pressure drops under load—limiting the ST’s true performance potential. Engineered for improved airflow, throttle response, and power delivery, this intake system is ideal for both stock and modified vehicles.
