Breather Plate, Ford EcoBoost 2.0L and 2.3L

Application :
  • Focus ST 2013 - 2016
  • Focus RS 2016

Engines create oil vapor from the crankcase and cylinder head that is usually recycled back through the air intake system. This vapor can create a buildup of carbon deposits on the intake valve that can reduce engine performance.

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

The mountune Breather Plate directly replaces the original engine block plate and features a 100% increase in baffle surface area over the original part. The increase in baffle surface area allows more crankcase vent vapor to be trapped and remain in the crankcase where it belongs. Additionally the route the oil vapor takes on its way to the intake manifold is significantly increased through the baffles resulting in an increase of deflection areas. At each deflection point, additional oil is removed from the vapor. Installation is easy and while not required the mountune Breather Plate can be used with many catch can systems on the market. This part is a must for high boost, high performance applications.

  • Essential on modified engines
  • Direct replacement
  • Easy installation
  • Machined from solid aluminum with precision steel baffles
  • Hard anodized durable finish

Excellent product February 14, 2017
Reviewer: Tyler Cookson from Virginia, USA  
Was back ordered, but was notified as soon as it shipped. Obviously a quality item, and well worth the money. I have a new RS with about 2700mi on it, and could see the backs of the valves were dusted with oil (coked on).

Product installs with no issues, just remember to cut the little stub on the gasket. You will see it when you transfer it over, it will be very obvious where you need to snip. I suggest using a razor blade and just taking your time so you do not slice the rubber gasket itself.

Mountune breather playe October 30, 2016
Reviewer: Bryan from TULSA, OK United States  
Installed on a Focus RS. As usual, excellent in form, fitment, and function. A little time consuming to install (you have to remove the intake manifold), but it's a very easy job. Don't be intimidated! When compared to the stock piece, it's obvious how much more effective the Mountune plate is. I coupled mine with a UPR baffled and valved catch can. The combination of the Mountune plate and baffled catch can should all but eliminate oil build up on the intake valves. We'll see soon enough...

Must Have for boost Applications October 14, 2016
Reviewer: Christopher Ayres from Livonia, MI United States  
We have all seen Focus ST intake valvestems coated in Oil. This will help greatly in that not happening, no catch can needed, but recommended. Easy install and well worth the cost for added protection.

Well built, relatively easy install September 29, 2016
Reviewer: Adam from Plano, TX United States  
I am hoping to reduce the goop I found in my piping during my turbo install. One often suggested way is to use a catch can, but I liked this approach of expanding on the existing vapor filtering strategy by increasing the baffle surface.

Did it work? I can't say yet, but the logic makes sense and the part itself is top notch.
