1-0103-1-FB Baffled Billet Valve Cover Breather compatible with 2013-2018 Ford Focus ST/ST250 (Flat Black)

Very high quality product! I’m glad to have the peace of mind that my engine is venting excess pressure. My car definitely feels less choked and smoother since I installed this.

Great quality product and design. The check ball is why I chose this breather as there’s no worry about boost or vacuum leak. CFM also is great about talking to customers and answering questions on forums. Would recommend to anyone looking to help protect their motor

Looks amazing while keeping unwanted crankcase pressure at bay. It’s a must have.

Very well built, fit perfectly.

Vendedor exelente

Bought this for my Focus ST. I have read alot about it at various forums and decided to pull the trigger. It looks good.

CFM will claim the ball and the screen cannot fail. That point being I’m not sure if it’s a case of failure in those, or just a product that was never going to work in the beginning with the ecosboost design and direct injection… I went from Ford’s solenoid BS setup (sounds nice hearing the blow off valve a lot) to running the true vacuum which rarely ever has my blow off valve going off, .. it goes off now only under mega boost when I abruptly let off of the throttle, and that’s STILL when oil makes its way out the CFM breather hose. it only happened when I really got on the throttle and let my blow off valve do it’s thing before, but still does now…. You have something that’s at the top of an engine that’s creating vacuum under load sure, and the ball is in place at that point. but as soon as you let off the throttle at the top of the RPM or even near higher rpms under WOT the blow off valve releases all of those gases to the atmosphere and wouldn’t ya know that the little ball does the same thing and rises up when with no pressure holding it down, allowing oil to spray upwards out of the filter… Your first week you might just notice your breather filter being a little more oil soaked but after that it’s got nowhere to go and just decides to leak all on your engine cover in on anything around it or under it. I even clamped it on there to no avail…. Bad design for releasing crank case pressure in the direct injection ecoboost.Instead of it just works type thing I’d love to see someone who works at explaining the science on how this is going to not let oil still vent to the atmosphere regardless of a screen that oil can clearly make its way through, and a ball that is only down in place when you’re under throttle but your blow off valve goes off when you’re off throttle and that when it decides to let all that oil come out the cap. We aren’t talking a quart a week but it’s not normal for this to happen and I noticed someone on a forum from CFM blaming the car owner. Pretty bad representation.

Product is pretty high quality but it appears to allow oil to splatter out of it as it splattered onto the intake of my focus st. I smelled burning oil and it came out of the baffle. I'll try using a hose clamp but it doesn't seem like this is gonna work for my st. And m engine is pretty new 16000 miles
