The AIRTEC Motorsport Hot Side Lower Boost Pipe is designed to improve airflow for the Fiesta ST 180. It replaces the restrictive standard boost pipe, featuring a larger diameter and smoother bends to enhance air movement. This pipe is suitable for both standard and re-mapped Fiesta ST models and fits with stock and AIRTEC intercoolers. Installation is straightforward, taking less than 30 minutes, and it connects to standard boost hoses.

Show original supplier description

Improve airflow and remove restrictions with the AIRTEC Motorsport Hot Side Lower Boost Pipe, specifically engineered for the Fiesta ST 180 and ST200 models (2013-2017). This boost pipe replaces the factory component, which features restrictive bends and a smaller 42mm diameter, with a larger 52mm diameter pipe for significantly smoother air transit. The "hot side" placement means it works with your existing intercooler, being compatible with both stock units and AIRTEC intercoolers. It is suitable for both stock and re-mapped Fiesta STs. Installation is straightforward, estimated to take less than 30 minutes, and it integrates with standard boost hoses. This boost pipe is exclusively available in Pro-Series Black.
