CFM Performance now makes it easy to vent the crankcase on your Chevy 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.
