The mountune Cast Inlet Manifold offers numerous performance benefits, whilst also vastly improving engine bay aesthetics of the 2.3-litre EcoBoost engine used in the Mk4 Focus ST.

The mountune cast aluminium inlet manifold adds reliability to all big-power or higher boost Focus ST engine builds, together with adding a host of useful additional features.

The mountune inlet manifold allows owners to take advantage of the high-flow internals, optional additional map sensor location and a port for either a mechanical boost gauge or for water injection.

In addition, it has also been engineered to house four optimally located PFI / methanol injectors for applications requiring additional fuelling demands.

Supplied as standard with a thermal gasket to prevent heat transfer from the cylinder head, together with all required billet fittings, gaskets and hardware required for installation, as well as optional locating posts to easily run with, or without the OE engine cover.
