Fits MST FO-MK401 cold air intake system (Ford Focus MK4 1.5T EcoBoost 2018+)
Summary
Fitted MST's MK401 intake to a Mk4 Focus? This clear cover is the part that finishes it: a transparent lid made for that system's enclosure, closing it off while keeping the filter in view. It is a genuine MST Performance accessory built around the FO-MK401 cold air intake - an add-on for the system rather than a standalone Focus part, so match it to the intake on the car.
Best For
Focus MK4 1.5T owners running the MST MK401 intake
Enclosing the intake filter with the install still on show
Vehicle application: Accessory for the MST FO-MK401 intake system (Focus MK4 1.5T)
Fitment And Setup Checks
Before ordering, confirm the car runs the MST FO-MK401 intake - the cover is shaped to that system and does not fit the factory airbox or other intakes.

Frequently asked questions
Will this fit my standard Focus airbox?
No - it is made for the MST MK401 intake linked above, not the factory airbox.
Is it purely cosmetic?
It closes the system's enclosure with a clear lid - finishing the install visually while the filter stays visible.
