mountune Full Intercooler Upgrade Focus ST 2013-2018


CARB EO D-727-4

The mountune high performance intercooler upgrade kit for the Mk3 Focus ST includes everything you need to optimize the performance of your ST and is the foundation for further power upgrades.

Using a 14-row extruded lightweight tube and fin alloy core with cast alloy end tanks for improved flow characteristics, the mountune intercooler upgrade gives a substantial reduction in Air Charge Temperature (ACT) with minimal pressure drop, ensuring optimum charge air temperature and therefore power. The larger than stock, mountune intercooler is essential for sustained high speed or track use and is not as prone to heat soak as smaller intercooler cores currently on the market. The performance of the mountune intercooler upgrade has been validated through extreme air temperature and vehicle speed testing. Compared to the original intercooler, the mountune Focus ST intercooler upgrade reduced outlet air temperature by over 39% for the same given intercooler inlet air temperature. The mountune Full Intercooler Upgrade includes the complete charge pipe replacement for maximum performance and efficiency.

  • Cast end tanks for purposeful air flow management
  • No drilling is required for installation
  • Core size 29.5 in x 11.7 in x 2.0 in - more than twice the size of the OE intercooler
  • High quality brackets and hardware included

  • 44% improvement in pressure drop - 3.4kPa vs. 6kPa (250hp)
  • Will support high power applications including turbocharger upgrades
  • Pressure tested to ensure quality and performance
  • mountune logo can be applied with included stencil
  • Includes the complete Charge Pipe Upgrade and high performance hose clamps. Select color options when ordering.
  • 50 State Legal

Considerable testing and development revealed the need for a larger than stock and more efficient intercooler core to improve the performance of the MK3 Focus ST. mountune engineers have developed a considerably larger and more efficient tube and fin type core that retains the OE mounting locations. Lightweight cast alloy end tanks ensure improved intake airflow and include robust mounting points that do not require drilling for installation. Using a tailored intercooler core allowed the use of the OE intercooler hoses and piping that ensure superior NVH control when compared to typical silicone hose type installations. Additionally, excellent turbocharger response is maintained by retaining the OE intercooler track. The removal of the vehicle AGS (Active Grill Shutter) is required for the installation of this product. Each intercooler is powder coated in black to ensure years of corrosion free service.

This part has been designed and is intended for off-highway application only. Installation of this part on a vehicle that is driven on public roads may violate U.S. and Canadian laws and regulations relating to emission requirements and motor vehicle safety standards.

The Beast Intercooler December 12, 2018
Reviewer: Thomas Kozuch from Pearland, TX United States  
Everything shipped on time and was meticulously package. I was very impressed. It is evident mountune takes pride in their products when they use good quality shipping materials. Installation was a bit of work seeing as it was my first intercooler installation and the only thing I would have added was installation instructions for the hot/cold piping. After all is said and done I am very very very happy with this product! Great gains to my ST.  CAR FEELS LIKE A BEAST.  I also enjoyed the stencil. Hats off!
