CFM Performance now makes it easy to vent the crankcase on your GM LS series 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 check ball to keep unmetered air from coming through while the crankcase is under vacuum. In other words, this breather acts just like a factory oil cap under normal driving conditions and when you get into boost it will release any crankcase pressure present.
This kit also has an integrated baffle to help contain any oil particles present in the engine rather than saturating the filter element and eventually leaking through like many other kits in the market.
The filter element is washable and has a variety of top finishes for great looks. The pre-oiled cotton fiber traps dirt particles without restricting air flow.
Although this kit was designed for use in racing applications, it works and looks great on any engine compartment.

Great Great product!!!!!…..Fit perfect on 2015 corvette LT1 motor. (You need to send them a message or call to get one for this motor)Carbon fiber matched my other carbon fiber engine dress up perfect and my motor is heavily modified and needed the extra breather….Yuou can also block off inside and use just for looks if wanted
Stop running open breathers on EFI cars Great fix for boosted engines. Installed on turbo 427 LS Corvette. With the open breather in the valve cover, the AFR’s would spike lean when getting off the throttle. After CFM breather was installed, the spike is much less severe and does not last nearly as long yet pressure is still relieved under boost. Great idea and high quality build. Great alternative to open breathers
Good product. Works as advertised. Nice unit. Well constructed and it works as advertised. I installed this one on a high mileage LS2.
