The Mountune Full High Flow Intake for the Fiesta ST provides increased airflow along with a configurable design that adapts easily to future engine modifications and can be part of a complete end-to-end solution for your intake. While this engineered intake has been tested and validated on high-power engines, it also functions on otherwise stock vehicles and is the perfect foundation for future vehicle modifications.

Our alloy castings are manufactured in the USA from high-quality aluminum with an enlarged bore and cross-section, the design also features robust mounting brackets to ensure secure installation. While compatible with the standard turbocharger, we also offer a larger coupling hose for use with our MRX Turbocharger upgrade.
