Focus Breather Plate

Mountune Breather Plate to suit Focus RS & ST. 

The mountune Breather Plate for mk3 Focus RS and ST directly replaces the original engine block plate and features a substantial increase in baffle surface area over the original part.

This labyrinth-style baffle has been machined into the oil breather plate itself, substantially increasing the surface area compared to OE, which allows more crankcase vent vapour to be trapped and remain in the crankcase where it belongs.

Additionally, the route the oil vapour takes on its way to the intake manifold has been significantly increased through the labyrinth design, resulting in an increase of deflection areas. At each deflection point, additional oil is removed from the vapour.

Maintain the peak engine performance of your mk3 Focus RS or ST whilst adding provision to neatly expand your oil breather to include a catch can system.

Installation is easy and, while not required, the mountune breather plate also includes two ports to allow easy integration of many catch can systems on the market.

This part is a must-have for higher boost / high performance applications.
