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

Choose a 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 or m260 upgrade you can use our SMARTflash app to confirm your calibration suffix, or alternatively contact us to help confirm. The general rule is any calibration ending -C(any letter here) requires the version WITH. All other calibration suffixes, including all Puma ST & Mk8.5 Fiesta 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?

If your calibration ID ends K1BY-14C204-C(any letter here) 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.

Use the 'vehicle info' option within your SMARTflash app to check your calibration ID, or alternatively contact us using the link below to verify before ordering.

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.

    more airflow!

    It took me (with no mechanical experience) almost 3 hours to install with basic non-powered tools. (including time taking photos and learning) It was great to see first hand the measurement comparisions of the internal dimensions - the 1.5" OEM section verses the 2" end-to-end of the Mountune pipe. The fit and feel of the Mountune charge pipe is very strong and good quality - it's a shame I only see it when I remove the engine drip tray. Despite the restrictions of my stock tune, I feel the car now breathes a little better and the turbo flutter noise on throttle lift off slightly enhanced.

    Mountune Charge Pipe Upgrade.

    Very pleased with the presentation of the product, simple to construct and install. Pleasing increase in turbo noises, unsure on performance increase at this stage but acceleration does feel improved. Thanks.
