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 is supplied in two finishes and 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) Colour instructions are supplied.
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.
The highly-skilled engineers at Mountune identified an obvious performance and aesthetical improvement to all I5 engine’s through the creation of a cast inlet plenum.
