Cold Air Intake - Ford 13-14 Focus ST

The factory Focus ST airbox is designed with noise reduction in mind, not performance. Under high load conditions it generates a measurable pressure drop that costs power, even on a completely stock car. The Process West Cold Air Intake addresses this directly.

Best of both worlds.

Rather than a simple pod filter swap, the Process West system combines a low-restriction K&N pod filter with a purpose-built cold air divider and internal bell-mouth. This design captures the high-flow benefits of an open pod arrangement while retaining the cold air separation and consistency of a proper air box enclosure. The result is improved airflow, reduced intake temperatures, and more consistent power delivery under sustained load.

Complete kit.

High-volume pipework, custom moulded silicone hoses, and matching clamps are all included. The system works as a standalone upgrade or in conjunction with the Process West Intercooler system for a fully integrated intake solution.

A well-engineered intake upgrade that addresses a genuine weakness in the factory Focus ST setup.
