mk3 Focus ST TDCi - Boost Hose Upgrade Kit

The mountune Boost Hose Upgrade Kit for mk3 Focus ST Diesel (TDCi) features a substantial improvement in airflow compared to the original factory Ford system.

mountune’s engineers have optimised the charge air ducting and hot side charge pipe to noticeably improve the inherent pressure drop.

The boost hose kit is compatible with the original intercooler, mountune intercooler, and systems that use the original intercooler charge pipes.

All of our silicone hose range also benefits from the SamcoSport lifetime warranty, for added piece of mind.


  • High-flow stainless steel hot-side intercooler pipe
  • Nomex / fluoro-lined high-flow SamcoSport silicone boost hoses (3-piece kit)
  • Optimised performance - everything you need, nothing you don't
  • Lifetime silicone hose warranty against manufacturing defects
  • Hoses available in colour options: blue

For maximum performance, we recommend to use this with the mountune alloy intercooler upgrade.
