Alloy Intercooler Upgrade

This part does not affect the base vehicle warranty.

The mountune alloy intercooler upgrade includes everything you need to optimise the performance of your mk2 Focus RS and is the foundation for further power upgrades.

Using a 14-row extruded lightweight tube and fin alloy core with cast alloy end tanks for improved flow characteristics, the mountune alloy intercooler upgrade gives a substantial reduction in air charge temperature (ACT) with minimal pressure drop, ensuring optimum charge air temperature and therefore power.

The mountune alloy intercooler upgrade is essential for sustained high speed or track use, and is not as prone to heat soak as smaller intercooler cores. The performance of the mountune alloy intercooler upgrade has been validated through extreme air temperature and vehicle speed testing - and was the original equipment fitted to the limited edition Focus RS500 model.

Compared to the original intercooler, the mountune Focus RS alloy intercooler upgrade reduces outlet air temperature by over 35% for the same given intercooler inlet air temperature.
