Just for the record, My 2003 5.9 used one fuel filter I don't remember the part number or micron level. My 2012 used a 5 micro filter which is the same one listed for 2010 thru 2012 I believe the last numbers on the part code are 608. My 2014 uses two filters one is a water separator. The owners manual states to use the 3 micron filter. This filter is listed for 2013 thru 2014 and the water separator filter is a different number. The Mopar or Fleetguard brands meet the specs set by Mpar. The filters for my 2012 look like the one for the 2014 except for the micron filter value. The last time I had my 2012 in for an oil change the service guy at the dealer told me the only real engine problems they see with the CTD is bad fuel. So keep you receipts the warranty won't cover bad fuel.
