On the 4th and 5th Gen Cummins, the crankcase ventilation filter is prone to clogging,  the solution?  Remove it! Our 6.7 Cummins CCV Upgrade will replace the entire top half of your valve cover, not only reducing CCV pressure, but improving the overall aesthetic appearance of your engine bay.
 
Installing a CCV filter kit can have several advantages. By removing oil-rich crankcase air that vents directly into your intake, you can prevent carbon buildup which can lead to a host of issues.
 
Includes silver billet alumnium CCV plate that bolts in place of the filter and cover, silver billet aluminium oil fill cap cover,  CCV feed port,  all bolts and hardware needed.    Can be used with a catch can (coming soon)  or vented to atmosphere
