Intercooler Upgrade - Ford Focus ST

The Process West Intercooler Upgrade for the Ford Focus ST is the result of exhaustive design, engineering, and real-world validation — developed specifically to unlock the full potential of the EcoBoost engine.

Engineered from data. Early datalogging of the tuned factory ECU revealed clear limitations in the factory hardware. It became evident that getting the best from the Focus ST required carefully developed hardware working alongside the latest aftermarket tuning — not software alone.

Bigger core, better cooling. At 550 x 390 x 65mm, the intercooler core maximises cooling surface area without sacrificing flow. Low-restriction end tanks and a highly finned open core design ensure exceptional airflow and cooling capacity, with enough headroom to support even the most ambitious power targets.

Complete kit. Includes matched 63mm intercooler piping, Process West silicone hoses, and high-durability hose clamps for a fully integrated, factory-quality finish.

A complete cooling solution for the serious Focus ST build.
