CFM Performance Baffled Billet Valve Cover Breather compatible with 2011-2016 Ford F-250 F-350 6.7 Power Stroke Diesel (Gunmetal Gray)-Fast Shipping

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
