CFM Performance now makes it easy to vent the crankcase on your engine with our new billet valve cover breather kit. This kit is a direct replacement for your factory oil fill cap and allows unwanted crankcase pressure to exit.
Our breather is the original on the market to incorporate a one way check-valve, keeping unmetered air from entering while the crankcase is under vacuum. In other words, this breather acts just like the factory oil cap, sealed under normal driving conditions. Only until positive pressure becomes present does the breather open to vent unwanted crankcase pressure.
This breather also has an integrated three-layered baffle and stainless steel mesh disc media to help contain oil particles that are carried by the crankcase pressure.
Our filter elements are washable and can be re-oiled similar to most aftermarket filters. Our large selection of high quality finished filter tops will be sure to add some style to your engine bay.
Although this breather was designed for use in racing applications, additional crankcase pressure ventilation is beneficial for any motor. Plus, our breather looks great in any engine bay!

Update: company sent a new o-ring and no longer leaks!Consistently comes loose and cause oil to leak all over engine bay. Customer service not helpful

I previously had one of these from a different company and had zero issues with it coming loose or anything. Decided to buy a new one due to dropping it and being dented. This one constantly comes loose and IS INSTALLED PROPERLY. Like it just tightens into the valve cover you can’t mess that up. Do not recommend

It was not a tough fit like a different brand I have. Maybe it is the o ring but not too happy with how it sits.2012 built speed

Metal looks good, but rubber needs extra grip

Bought it and installed. Worked great for the first few days and helped with my crankcase ventilation. Few days later it fell off/blew off during a pull and covered my entire engine bay in oil. I had the thing on as tight as it would go. I was worried that it didn’t feel as tight as the oem cap but didn’t think much of it.
