When I purchased my Crossfire four years ago from a Chrysler dealership I made a point of replacing all filters (air, fuel etc.) including all fluids (oil, coolant, brake). When asking about the Cabin Filter, the parts guy couldn't find a part number...he then cross referenced on another computer...and said "nope, your car doesn't have a cabin filter...let me run your VIN to double check". He then reported that no Cabin Filter is listed for my make and model....I believed him! Four years later I am now replacing the Cabin Filter with what is likely the original! Purchased a Fram from my local supplier. Fram has partnered with Fresh Breeze;

If you haven't replaced the filter before...this is helpful.
