Alloy Intercooler Upgrade - RS

The mountune Alloy Intercooler upgrade includes everything you need to optimise the performance of your mk3 Focus RS and is the foundation of further power upgrades.

Using a 11-row extruded lightweight tube and fin alloy core with cast alloy end tanks for improved flow characteristics, the mountune alloy intercooler upgrade gives a substantial reduction in air charge temperature (ACT) with minimal pressure drop, ensuring optimum charge air temperature and therefore power.

The mountune alloy intercooler upgrade maximises performance within the RS' restrictive packaging space. It features mountune logo detailing on the end tanks and is available in a powder coated black finish, complete with optional mountune core-logo in yellow or white (for an additional charge).

The intercooler is also supplied with cooling pack air deflectors that clip in to the rear of the lower grille, aiding optimum airflow through the core.

Core dimensions:

  • OE: L616mm x H198mm x D80mm
  • mountune: L640mm x H215mm x D122mm


  • Superior tube and fin core construction (72% larger volume than OE)
  • Cast end tanks for purposeful airflow management
  • No drilling or modification required for installation
  • Powder-coat finish in satin black - with optional mountune logo
  • Includes cooling pack air deflectors
  • Works in harmony with mountune Charge Pipe Upgrade Kit

    New Mountune intercooler

    I Have had fitted my new Intercooler and charge pipes, I must say I am very happy the way its looks on my Shadow Black MK3 RS. I think there is a noticeable difference with the power delivery with the FPM 375.

    Mountune boostie beastie

    Fitted Intercooler and boost pipe kit with hard pipe today !! Did not expect any real changes to RS running the FPM 375 but I must say there’s real noticeable difference in the boost !! From 2000 rpm to 4000 rpm on full throttle boost runs around 60% max then when you hit 4000 rpm to 6500 rpm it’s can hit 80/90 % on the gauge !! Doesn’t back off until you hit the Red , I could feel it tail off before upgrade for sure !!!! Definitely worth the upgrade and ready for the 400 upgrade next !!

    Mk3 intercooler

    Had to wait to be in stock as I wanted it logo free. But once I ordered came next day. Well built and a great addition to the RS.
