mountune'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 appropriate size for the 2.5-litre engine.
The mountune I5 cast inlet plenum has fast become the market-leader in the I5 cast inlet plenum sector with good reason; proven performance benefits across a multitude of power outputs, durable construction, OE packaging for ease of installation on mk2 Focus RS, mk2 Focus ST and various Volvo models - all combined with the assurance of buying from the best in the business and a name you can trust - mountune.
The I5 cast inlet plenum is supplied in two finishes, natural silver and "RS500" black, and comes supplied with the required hardware for installation. Fitting takes less than 30 minutes on a mk2 Focus RS and approximately 60 minutes on a mk2 Focus ST (recommended removal of OE induction assembly). Colour fitting instructions are supplied.
Output improvements will vary on non-mountune upgraded vehicles, dependent on specification of tune, calibration and boost level being run.
But hard to fit but worth it in the end
This is a well made bit of kit. Fitting is a pig be prepared to lose skin blood and sanity. But this is not Mountuns fault. Now it could be in my mind but I am sure that there’s more power and torque over 4 thousand revs. Well worth it.
Very good product but took ages for the black one to be in stock!
