Replace the crankcase breather on top of the valve cover assembly on '03-'05, 5.9L Dodge Turbo Diesel trucks with this replacement filter from Cummins.

The vent filter includes a new O-ring for installation.

NOTE: Will not work on '06-'07 trucks. Cummins says you have to buy a new complete valve cover to replace the CCV filter on these trucks.

Geno's was excellent to work with and the part was exactly what I needed. Will definitely be doing business with Gens's again. So happy to have found a great place to get parts for my Dodge Ram Cummins.

Great Company

Looked all over for the right filter for one of our Cummins trucks. Auto part store gave us the wrong one. Geno's had it in stock, for a good price. Shipped to our house and threw in an awesome cummins sticker. Would definitely recommend this company for you auto part needs.
