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 the factory oil fill cap and allows unwanted positive crankcase pressure to exit.

It is the first breather of its kind which uses 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, our breather works just like the 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 one with an integrated stainless mesh and disc baffle system to help maintain oil particles in the engine rather than allowing them to exit and saturate the filter element.

The filter element is washable and is offered with a variety of top finishes for great looks. Although this kit was designed for use in racing applications, it works and looks great on any engine compartment!
