AIRTEC Motorsport induction kit for MK4 Focus ST 2.3 EcoBoost



As part of our expanding Mk4 Focus platform product range, AIRTEC Motorsport is proud to launch our intake kit for the ST model to improve performance with a simple, bolt-on modification for track or fast road use.

This freer-flowing induction kit replaces the car’s original air box and restrictive intake set up. It features our Group A cotton filter that significantly improves the car’s breathing by increasing the amount of cold air it can take in, therefore offering increases power, performance and sound.

The filter is protected from warm air within the engine bay by a laser cut shield and the replacement intake pipe that comes as part of the kit has been increased in size to improve internal capacity. Made from aluminium, it also offers a smoother flow in comparison to the original pipework that varies in diameter.

The kit fits neatly in place of the original to improve the look of the engine bay and comes with all fixtures, fittings and instructions for a direct, bolt-on installation.

Its improved air flow, performance, sound and visual gains, as well as its straight forward fitment make it an essential modification for all modified Mk4 Focus ST models.
