Breather Plate [Mk3 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.

Features:

  • Designed and optimised for modified 2.0 and 2.3-litre EcoBoost engines
  • Direct replacement
  • Easy installation
  • Machined from solid aluminum with a precision machined labyrinth-style baffle
  • Twin ports facilitate easy installation of a catch can system

Technical:

It is well documented that direct injection engines, like the 2.3-litre EcoBoost found in the mk3 Focus RS, create oil vapour from the crankcase and cylinder head which is normally recycled back through the air intake system. This vapour can create a buildup of carbon deposits on the intake valve and can lead to reduced engine performance.

Additionally, over a period of time the oil vapour can accumulate on the intake hoses, turbocharger, intercooler and intake tract, slowing airflow and thereby further reducing performance. For optimised engine performance, the oil should be removed from the vapour before it reaches the engine’s intake system.
