Alloy Intercooler Upgrade [Mk8 Fiesta ST | Puma ST]

The mountune high-performance alloy intercooler for the Mk8 Fiesta ST and Puma ST provides the ultimate cooling upgrade for those wanting a fully optimised and data-backed solution, for the management of air charge temperature on their standard, or modified 3-cylinder EcoBoost engine.

Extensive temperature and pressure testing was carried out within an environmental test laboratory to ensure our revised design and core configuration was providing optimum cooling performance, yielding a minimal pressure drop across the core and ensuring no adverse affect to the upper cooling pack's ability to maintain engine coolant temperature (something a full-height intercooler can negatively affect).

Using a custom-built high-performance 8-row extruded tube and fin core to both maximise the available package space and to ensure the perfect balance of performance - reducing air charge temperature and also to ensure efficiency in terms of pressure drop across the core, the mountune alloy intercooler upgrade excels in both, as validated in temperatures ranging from 0ºC - 40ºC.

The OE intercooler end tank design is not very efficient, so as well as ensuring the perfect core type and size was utilised, high-flow end tanks were designed that also improve airflow and further assist with ensuring the best possible pressure drop across the intercooler, compared to OE.

No cutting or modification is required to the OE cooling pack during installation and the intercooler, which is finished in a durable black powder coat, is also supplied with a 'mountune' stencil for you to easily add a logo, should you desire.

More detailed test data can be found below, but here's the key performance highlights:

  • 44% larger core volume
  • Almost twice as efficient as the OE cooler*
  • Highly capable in hot climates (outlet temps only 14.8ºC above ambient even at 40ºC)
  • High-efficiency core and end tanks improve the nominal pressure drop seen across the intercooler compared to OE
  • Upper and lower air scoops ensure an enhanced level of airflow through the core

*at ambient temperatures ranging from 0ºC - 30ºC.

Features:

  • Superior tube and fin construction
  • No drilling or cutting required
  • Black powder coated finish 
  • 44% bigger core volume over OE
  • Works in harmony with Fiesta ST m235 Upgrade Package
  • Supplied with 'mountune' intercooler stencil

The mountune intercooler also forms the foundation for an expanded range of airflow and oil cooling enhancements that have been engineered to work together in perfect harmony, due for release in Q3 this year.

    Great piece of kit!

    Had to wait a while for it to come back in stock, and fitted this and the ACAI at the same time. Looks great, easy to fit...getting bumper off was ok, putting it back was a 2 person job to prevent any scratches. Perfectly enhances the other upgrades being M235,throttle elbow, air intake etc...now just need the lowering springs to complete the upgrade.

    Beautifully made

    Beautifully made. Fits perfectly. I would have preferred printed instructions with photos, tools required and approximate timing like many of Mountune’s other products, but the online videos are easy enough to follow. I would like to spray paint the Mountune logo, but I’m not sure what paint to use. Haven’t pushed it yet, but I’m sure it will perform well.
