I jus had to put injectors in my dads 06. Talked to a guy at the local dealer. He told me that dodge had admited that their filtration system was one of the plroblems for some injector s failing. He also said that the had pulled all the old fuel filters and replaced them with a new number and that number is a 2 micron filter. And finally said that there was a fleetguard filter that was a 2 micron. Both of which are drop in factory canisters. Just wat I was told. Sorry I don't have any part numbers at the moment.
