Heck yeah it does, I did the same thing to my 04 and all the new 06's at a former job, the cab fresh filters are well worth it, if you keep the ac on recirculate it helps keep it from sucking the dust out of the airbox into the wet evaporator where it turns to sticky mud too.

I thought the 90's CH and CL's had a filter in the heater/ac box that was replacable. The same thing goes for that truck, keep the AC on recirc it closes off the oiutside vent and keeps the dust out, or its supposed to anyway.
