mountune I5 Cast Inlet Plenum

Our Price: £562.50 (£675.00 inc vat)

Quantity:

Cast aluminum inlet plenum for the I5 engine (Focus ST, Focus RS, Volvo)

The highly-skilled engineers at Mountune identified an obvious performance and aesthetic improvement to all I5 engine?€?s through the creation of a cast inlet plenum.

Extensive CAD and CFD work allowed an improvement to be made - particularly around the port entrance to each inlet as well as to increase the volume of the plenum itself to a more appropriate size for the 2.5-litre engine.

The inlet comes supplied with the required hardware for installation; fitting takes less than 30-minutes on a Focus RS and approx 90-minutes on a Focus ST (due to the need to remove the standard induction assembly).

Substantial performance gains can be expected on all I5 engines - some example graphs can be seen here showing the typical improvement to a Mountune Focus RS MP350, and also a Mountune Focus ST MP260.

Output improvements will vary on non-Mountune upgraded vehicles dependent on specification of tune, calibration and boost level being run.

I had the Mountune i5 plenum installed to my Mondeo XR5T couple of months ago and its a solid performer.
