Airtec Enclosed Induction kit Ford Focus MK4 ST


As part of our expanding Mk4 Focus platform product range, AIRTEC Motorsport is proud to launch our intake kit for the ST model, suitable for track or fast road use.


Developed in-house at AIRTEC HQ in the UK, we’ve created a comprehensive solution to improving the car’s original air intake system to allow more flow whilst maintaining low intake temperatures, improving response, as well as sound and aesthetics within the engine bay.


Having previously designed a number of enclosed induction kits for other performance models, we were keen to develop an extensive intake package for the Mk4 Focus ST to offer significant improvements.


Featuring a huge, free-flowing cotton air filter that is housed inside a four-piece enclosure, the comprehensive kit also includes a replacement aluminium intake pipe. To ensure the new air filter does not suffer with heat soak issues from the confines of the engine bay, the laser cut heat shields provide a barrier from the heat of the engine and is fed cold air from the original front intake.


The result is increased power, improved throttle response, heightened induction noise and a more pleasing look to the engine bay.


The kit is a direct replacement that requires no additional drilling or cutting to fit, and comes complete with all the correct fixtures and fittings, as well as detailed instructions.
