Description
- CFM Performance valve cover 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
- Acts just like a factory oil cap under normal driving conditions and when you get into boost it will release any crankcase pressure present
