This full air box replacement induction kit is designed specifically for the Ford Fiesta ST mk8 1.5 Ecoboost.
This kit allows for increase in airflow and induction noise over the factory intake equipment.
The heat shield replaces the factory air box and mounts to standard OEM mounting points, it also replaces the standard intake hose.
Whilst an ECU remap is not required, it will help you make the most of the increased potential airflow.
