As with any upgrade of this type, additional strain is placed upon your engine and drive train. While we have thoroughly tested and validated this upgrade without issues, additional power, cylinder pressure and temperatures may cause engine damage and/or complete failure. It is advised that you upgrade your internal engine components and drive train to support the additional power and performance. For motorsport and track use, it is strongly recommended to upgrade your engine internal components to avoid catastrophic engine failure. This product is for race and track use only.
The mountune Fiesta ST Induction Upgrade includes a uniquely constructed aluminum air box with a secondary cold air feed point. Additionally, the air box has been engineered with features that reduce the delta pressure drop by 2kPa that when coupled with the included mountune high flow air filter, provide a 21% increase in airflow. The mountune Fiesta ST Induction Upgrade provides the foundation for further performance upgrades with an engineered approach that retains the OE appearance and reliability while providing a rich, deep induction note that reflects performance.
- Powder coated aluminum air box base
- mountune high flow air filter
- Additional cold air feed
- Easy installation
- Retains original air box cover
The Mountune High Performance Intercooler Upgrade for the Ford Fiesta ST includes everything you need to optimize the performance of your ST and is the foundation for further power upgrades. Using a 7-row extruded fin core with inner-fin tube design gives a massive improvement in both Air Charge Temperatures and pressure drops ensuring optimum charge air temperature and increased power. Our intercooler also maximizes available vehicle package space while retaining the essential air management ducting for the Ford cooling system.
- CARB EO D-727-4 (CARB approval applies to intercooler only)
- New improved design
- Cast End Tanks
- No drilling required
- Durable Black powder coated finish

The packaging for the OE intercooler and radiator on the Fiesta ST is very compact leaving little space to effectively and safely install an upgraded intercooler. The mountune intercooler upgrade was engineered to retain the original Ford cooling pack or air ducting system. This helps maintain engine cooling temperatures thereby avoiding "over-heat" conditions that reduce engine power. Removal of the vehicle's original cooling pack and using a larger intercooler core would cause a dramatic increase in engine coolant temperature, inducing engine protection software strategies that reduce engine power for protection.
