Charge Pipe Upgrade Kit [Mk8 Fiesta ST | Puma ST]

Re-circulating Valve

The mountune high-flow charge pipe upgrade kit for the Mk8 Fiesta ST and Puma ST removes the multiple inherent restrictions found in the OE hot-side charge components, substantially improving airflow and reducing the pressure drop across the system.

The complex OE component features multiple sections which taper down or narrow, reducing the pipe diameter by as much as 50% of the turbo outlet / intercooler inlet pipe diameter and also incorporates a restrictive sound resonator.

Carefully engineered to be a direct replacement fit, the mountune charge pipe kit includes everything you need to replace this power-robbing section and is the only option currently available that addresses the super-restrictive upper hard pipe; increasing airflow by a massive 62% versus OE!

The aluminium hard pipes are supplied in our durable and aesthetically pleasing black anodised finish and is available to support ST models both with, and without the factory re-circ valve. Not sure which you need? If you're running our m235 upgrade you can use our SMARTflash app to confirm your calibration suffix, alternatively please follow our guide using Ford's ETIS system below. All Puma ST models require the version WITHOUT.

An essential upgrade for those wanting to improve the performance and efficiency of their engine, provide headway to the turbocharger, or that want to achieve maximum power and torque output.

Kit Contents:

  • High-flow aluminium upper hard pipe
  • High-flow aluminium lower hard pipe
  • Silicone elbow
  • Replacement pipe securing clip
  • 2 x Jubilee clips

Please note: When installing this kit, ensure you re-use the seal found in the OE upper hard pipe.

Not Sure Which You Need?

Simply follow the FORD ETIS link below, then:

- Click on 'Vehicle'
- Enter your Registration / VIN
- Click on 'View PTI Information'
- Click on 'PTI related Electronic Control Units Installed on this VIN'
- Check the suffix under 'Powertrain Control Module - SoftwarePartNo'

If yours ends K1BY-14C204-C* you need the version WITH.

If yours ends K1BY-14C204-EA or K1BY-14C204-EB you also need the version WITH.

If your software part number corresponds to any of the following, you need the version WITHOUT:

K1BY-14C204-EC onwards

All Puma ST models require the version WITHOUT.

When Size Really Does Matter...

A side-by-side comparison of the upper hard pipe section reveals just how restrictive the OE component is versus the mountune high-flow replacement.


Fully instrumenting our development vehicles allows us to constantly collect and analyse critical engine and ancillary data, but we also like to extensively test individual components on the dyno and if relevant on the flowbench.

Typical gains in back-to-back testing revealed a substantial increase in airflow of 62% versus the OE unit, giving you additional headway and improving your engine's efficiency.

    Typical Mountune. Can see and feel the quality of the components and it fits perfectly. No swearing at all!

    M260 here we come

    The final piece of the puzzle to enable the M260 upgrade on my Fiesta ST. Great finish and really well packaged as always.
