I5 Cast Inlet Plenum [Mk2 Focus RS/ST] Power cylinder bore wear and noisemountune's highly skilled engineers identified an obvious performance and aesthetical improvement to all I5 engines through the creation of an I5 cast inlet plenum. Extensive in house CAD and CFD work (by the same team responsible for producing mountune's BTCC, WTCC, WRC and Rallycross inlets) 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
