Carbon Induction Kit [Mk4 Focus ST | Mk4 Focus 1.5]

The mountune carbon induction kit for Mk4 Focus ST and Mk4 Focus ST-line 1.5-litre (pre- and post-facelift) includes a beautifully designed high-flow carbon fibre assembly, which, combined with its natural heat-resistant properties and the large dual-entry air filter, provides virtually uncompromised airflow to the 2.3-litre EcoBoost and 1.5-litre Dragon engines.

This kit includes a large carbon fibre air feed that both evenly distributes cold air from the front of the car around the filter body and also acts as a thermal barrier, preventing unwanted engine bay heat from reducing engine performance.

In addition to the front feed, this kit also includes a porous lower hose which mounts to a lower cold air entry point in the bottom of the heat shield and picks up an additional cold air feed from a low-pressure area behind the bumper - a design feature originally developed and utilised by mountune on Ford-endorsed intakes over the last decade and a half.

The mountune carbon assembly is fully rubber mounted to provide compliance to the native engine movement, preventing unwanted interference or rubbing and is supplied with a comprehensive selection of installation hardware for hassle-free fitting.

Engineered to deliver the ultimate in performance and sound for owners wanting the open cone aesthetic and sound, without compromise.


  • Matt carbon fibre air filter assembly
  • mountune high-flow dual-entry cone air filter
  • Aluminium / carbon fibre cold air feed options 
  • Porous secondary cold air feed (protects against hydrolocking)
  • Stainless hose clamp
  • Supplied with all required hardware
  • Suitable for vehicles at all stages of tune - recommended for EcoBoost vehicles running 365PS / 560Nm and above
  • Recommended to be used with the mountune carbon fibre rear intake when used on 2.3-litre EcoBoost applications.

Please note: as carbon fibre uses a man-made manufacturing process, small differences in the finish of parts is normal.

    Carbon Induction Kit [Mk4 Focus ST]

    Definitely more power and sounds more aggressive, once again, an ingenious creation by mountune

    Outstanding quality.

    Another simply stunning bit of kit. Looks fantastic and compliments the carbon rear intake perfectly. It's very well thought out and easy to build and install. Not only does it look great but the sound it produces is awesome. Compared to another induction kit I had installed previously this one sounds better in every way. More induction whoosh, lots more lift-off BOV type sound and even some stutututu. Could not be happier!
