Valve Cover Breathers

Sort by:

Now available for Dodge/Chrysler/Jeep, GM and Ford applications!

CFM Performance valve cover breathers are the best money can buy and is the reason they have become extremely popular so quickly. They are so much more than a pretty filter on top of your valve cover and offer features that no other kits offer.

It is the only breather on the market which incorporates a check ball to keep unmetered air from coming through while the PCV system is active and the crankcase is under vacuum. In other words, this breather works just like a factory oil cap under normal driving conditions but will vent any positive crankcase pressure present under full or part throttle. It is also the only breather with an integrated baffle to help contain oil particles in the engine rather than allowing them to exit the valve cover and saturate the filter element. Filter tops are available in several popular powdercoat finishes, chrome, hydrocarbon and select OEM colors.

CFM Breather Features:

Relieves positive crankcase pressure
Direct replacement for oil cap
One-way check ball for MAF based cars
Internal baffle separates oil/air
Retains factory PCV system
Made from 6061 aluminum
Cleanable breather filter
Numerous finish options

Testimonialsfrom Fans and Enthusiasts

Just wanted to let you guys know that I am really impressed with your store. I just purchased over $1,000 worth of parts for my Focus and will definitely be back for all my performance needs. Like I said I am really impressed with your service and will definitely spread the word to the Focus community here in Indy.
- Zach R.

I would like to thank you very much on the prompt delivery of my order. It blows my mind to see it arrive in 2 days. Again, thank you very much. I will always shop for my Focus parts through c-f-m.
- Patrick B.

Talked to William on the phone and he was great help! Received the order and I can honestly say, I am very pleased with your customer service.
- Mike T.

Got the part on Tuesday and was very pleased with the quality of the CFM mount and the apparent care with which it was manufactured. The instructions were also very clear and effective. Thanks for making a great product and I look forward to purchasing more SVT products from you.
- Rene Y.

I have ordered many times from CFM Performance. I've never had an issue with shipping or with any of my products. Their prices are very good and they run sales from time to time to make them even better!
- Brandon C.

I've placed many orders with CFM for my rally Focus build and orders are filled very quickly and I receive the items in only a few days and I live in Canada eh! Well done CFM Performance. Looking forward to my latest batch of go-fast parts!
- Mike K.

Simply wanted to take a minute to thank your team for yet another quickly sent, well-packed and exact order I received a couple days ago. I had the parts successfully installed yesterday... by people that still can't believe I can obtain the exact same O2 sensor as their business but for half the price (even after having it shipped to Canada)! - Philippe G.

Just a quick thank you for another great online shopping experience with you guys. Parts received within specified shipping time and very well packed. I will use you again when the time comes.
- Danny C.

I've been wanting the Focus Builders' Handbook for a long time, and you guys carried it for a very reasonable price. I'm pretty sure I received it within two days of purchase (and it traveled from FL to NV!). With shipping and prices like that, I'll definitely be ordering from you guys again! - Aaron B.
