Process West Upgrade Intercooler Kit Black Ford Focus ST 2013-2018 | PWFMIC05B

The Process West Intercooler Upgrade for the Ford Focus ST is a fully engineered cooling solution developed through extensive design, datalogging, and real-world validation. Built specifically for the EcoBoost platform, it addresses the limitations of the factory intercooler and supports reliable performance gains on tuned and stock vehicles alike.

Engineered from Data, Not Guesswork

Early datalogging of the factory ECU highlighted clear thermal and airflow limitations in the stock intercooler system. These constraints become more pronounced under increased boost and tuning, where intake air temperature control becomes critical to maintaining consistent performance.

The Process West solution was developed to work in harmony with modern aftermarket tuning strategies, ensuring the hardware supports the software—not the other way around.

High-Capacity Core for Maximum Cooling

The intercooler core measures:

550 x 390 x 65mm

This design prioritizes both cooling efficiency and airflow capacity, delivering:

• Significantly increased cooling surface area
• Low-restriction airflow characteristics
• High thermal efficiency under sustained load
• Headroom for higher power applications

The open, highly finned core design works to efficiently dissipate heat even under demanding driving conditions.

Optimized End Tank Design

Low-restriction end tanks are engineered to promote smooth charge-air distribution across the entire core. This helps reduce turbulence and pressure drop, allowing the turbocharger to operate more efficiently.

Complete Integrated Kit

The system is supplied as a complete bolt-on package, including:

• Matched 63mm intercooler piping
• Process West high-quality silicone hoses
• Heavy-duty hose clamps

This ensures a factory-quality fitment with improved durability and airflow performance.
