Cabin Filter
 

Just wondering, where is the cabin filter on a 2001 2500?

There is none.This is what most people put on there trucks and it works well I have it on mine.CAB FRESH - FILTER KIT ('94-'02 DODGE)-Dodge Cummins Diesel Truck Accessories Geno? Garage

I saw that on Genos Garage. Where does that go?

They attach to the plactic cowl under the winshield wipers.You have to remove the wiper to put them on.

Alright thanks! I just ordered the kit.
