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 screw-in oil fill cap and allows unwanted crankcase  pressure to exit.
	    
	        
	  The proprietary internal baffle substantially reduces oil  particle travel without affecting air flow. A double-seal O-ring is used to  reduce the amount of force needed to create a positive seal, increasing seal  life and eliminating leaks. 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.
