AIRTEC Motorsport Big Boost Pipe Kit for Mk4 Focus ST
Enhance the performance of your Mk4 Focus ST with the AIRTEC Motorsport Big Boost Pipe Kit. Designed for track or fast road use, this comprehensive 11-piece kit is developed in-house at AIRTEC HQ in the UK.
Constructed from lightweight aluminium, the three pipes in this kit offer improved strength to withstand higher boost pressure. The kit also includes six Pro Hoses silicone joiners and two CNC-machined connectors for easy installation.
On the hot side, the original pipework with a 55mm internal diameter and a restrictive indented section is replaced with a 60mm internal diameter pipe, ensuring unrestricted flow. For the cold side to the throttle body, the original pipework with a 55mm to 63mm taper is upgraded to a consistent 63mm internal diameter, increasing both flow and capacity.
No additional drilling or cutting is required to fit this kit, as it comes complete with all the necessary fixtures and fittings, along with detailed instructions. Improve the boost pipework’s flow and efficiency with this must-have upgrade for any modified Mk4 ST.
