Fresh Air Filter?
i do believe there is... but i've never heard of anyone switching it out. if it would be anywhere it would be between the windshield and the hood. in that area i think. i'd check out the the christmas thread to see if there is one.
It's commonly known as a Cabin Filter. I don't believe the 2nd gen Rams came with them, but you should be able to get a filter from Fram (look it up in their book) and install it.
I know the 3rd gen Rams have a factory option for the cabin filter.
