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 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.
The proprietary internal baffle substantially reduces oil particle travel without affecting air flow. 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.
NOTE: This breather potentially fits many VW / Audi applications which use the OE 06K103485A oil cap (shown in photos). MUST MAKE SURE THERE IS AT LEAST 2.5" CLEARANCE FROM VALVE COVER TO UNDERSIDE OF HOOD. Breather filter requires at least 3" diameter hole to clear engine cover.
