Anyone know if a 98 supercab would have a cab filter for the HVAC system? The truck was bought new by my Father-In-Law, doubt he ever had it changed. If so, where is it? Thanks in advance. Tim

 

I have a 98 Supercab and as far as I know it does not have one.

 

Bingo, I was curious about the same thing, turns out I was chasing a ghost. My solution to filtering the cab air? I stopped smoking. It didn't smell bad even when I did because I always had the window down, but I guess this filter helps that in things like Expeditions and Navigators I think.
