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.
This breather is the ONLY one in the market which incorporates a one way check ball to keep unmetered air from entering while the crankcase is under vacuum. In other words, this breather acts just like a 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 kit 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!
