The Mk4 Focus ST hides a lot of pace behind a very ordinary factory inlet hose, and this MST Performance part swaps that restriction out. It is a precision-made, high-flow direct replacement for the original hose on the Focus MK4 ST from 2019 - genuine MST hardware that bolts in where the factory part sat, leaving the rest of the intake standard and the upgrade fully reversible.
Best For
Mk4 Focus ST owners starting on intake hardware
Cars already running or planning a remap
A weekend-fit upgrade with no fabrication involved
Keeping the engine bay tidy and serviceable
Sorting The ST's Intake Tract Piece By Piece
MST covers the Focus Mk4 range with model-specific intake parts. This hose is the ST application; the 1.5T Focus runs its own MST inlet pipe - so match the part to the engine rather than the bodyshell.
One application: Focus MK4 ST, 2019 on. Confirm your car is the ST rather than another Mk4 engine - the 1.5T uses a different MST part - and check the part number before ordering.

Frequently asked questions
Will this fit a non-ST Mk4 Focus?
No - this hose is specific to the MK4 ST. The 1.5T Focus has its own MST inlet pipe, linked above.
Is it a straight swap for the factory hose?
Yes - it is made as a direct replacement, so it fits where the original hose sat with no cutting.
