Cabin filter for 06 GMC 2500HD

My 06 doesn't have a cabin filter. Is it possible to install one from another year GMC ?

Thanks

No. Cabin filter was eliminated starting 2003.

Yes, of course you can. The space is there and a stock filter and filter cover will fit. Just cut a hole and you're good to go.

Yes, you can cut a hole in the right spot to insert the filter, and you can buy (or even 3d print) the cover to hold it in place.

From googling, I found these two, but I'm not sure if they will work for your truck.

newdude is right, the cabin air filter was eliminated in 2003. The space for it is still there, but the HVAC box mold was changed on some trucks and there is no retrofit kit available (have to make your own like the guy in the video did). On others the access panel is there, GM just didn't put a filter in it. It all depends on which vendor the box came from, Delphi or Visteon. There is an AC Delco retrofit kit for adding a cabin air filter to the 2007 and newer GMT 900 trucks, but it does not work on the older trucks.
