i haven't searched for one, or even checked the owner's manual. but...i seriously doubt there is a cabin air filter.

 

The air filtration system is a dealer-installed option, not available from the factory.

 

As noted earlier the cabin air filter is not standard. If it was installed by your dealer then look under the dash in the area below the glove box. There is a plastic cover that needs to be removed to get access. If installed there will be rectangular piece on the bottom of the heater box held in place by about 6 screws. That is where the filter will be. If it wasn't installed by the dealer you will just see a rectangular area on the bottom of the heater box that can be cut out to install the filter.

 

I have a Gen 1 Supercrew. Anyone know where this filter is?

THanks,

Chuck
