The Airtec Stage 2 intercooler for the Ford Focus MK2 ST was developed for fast road and track use and delivers significantly better cooling and performance than the standard intercooler.

This upgrade is based on a large 60 mm core which is greater in height and length than OEM, combined with a air ram scoop which actively forces cold air through the intercooler. This ensures lower intake air temperatures, more power and consistent performance, even during prolonged hard driving.

Thanks to the bolt-on installation Does this intercooler fit directly onto the original boost hoses without any extra modifications?.
