What is the best intercooler for my Ford Focus RS?
We recommend the new COBB Tuning intercooler and the very popular ETS front mount intercooler for your Focus RS. Upgrading your inter-cooler helps eliminate heat-soak and it improves your air charge temperatures.
With that in mind, we also recommend that you upgrade the restrictive factory intercooler piping. In our experience, the shape, diameter and materials that make up your factory piping limit your RS's ability to make more power. By upgrading your piping, you improve air flow and gain horsepower.
