Blessed Performance has the Pusher 3/4" CCV Breather Filter.
The Pusher CCV filter is a great way to clean up the external OEM CCV setup on your off road tuned 6.7L Cummins equipped RAM trucks. The factory CCV filter built into the valve cover works fairly well but doesn't capture 100% of the oil mist. Add this filter to capture the rest and eliminate all the external CCV components.
