This aluminium boost pipe for the FORD FOCUS MK3 ST and RS replaces the original hard plastic section, including its silencer.
The larger 63 mm pipe diameter, combined with removal of the silencer integrated into the original part, provides not only a spectacular 91% increase in airflow and a 90% increase in flow speed (measured on a flow bench), but also smooth, turbulence-free airflow. These properties also make the product suitable for vehicles with increased power.
The boost pipe is compatible with the original intercooler.
