I can't tell you about aftermarket filters but the MB part number for the fleece is A000 180 26 09 and the Mopar number is 05102905AB , dealer cost is $18.55 and they want to make money so dont expect to buy them much under $26.00 or so. I have access to live stocking information and there is plenty in the Mopar and MB system so don't listen to all the part number change stuff.
