Maintenance free CCV filter for 2021 Cummins?
We are already getting word that the L9 and B6.7 will have a maintenance free crank case breather/filter for 2021 along with several other updates. If this carries over to the Ram trucks(which it likely will), then no more CCV filter replacement ever 67k miles. The ECM will also be updated to CM2450 and will have increased computing capabilities which likely means more fuel maps for greater efficiency in more scenarios.
For those that do not know, 2021 is the start of phase two of the EPA's crack down on emissions in diesel trucks. Phase one for the past few decades has been centered around the emissions of these vehicles and phase two is increased fuel economy standards which these trucks have been exempt from until now. This is one of the main reasons why diesel manufacturers are adding things like 10 speed transmissions, higher pressure injection pumps, tighter clearances, and thinner oil. They all increase fuel economy/efficiency and they will need it now that EPA fuel economy window sticker estimates will be required just like the vehicles under 8,500 GVWR.
