cabin air filter

check behind dash glove box. or under wiper compartment

There is no Cabin Air Filter from the factory. You may add one yourself. Many shops sell "kits" to do that. You have to cut out the plastic plate out where the filter should go. Then insert the cabin air filter and place a cover over the filter.

It does not have a cabin filter, I repeat DOES NOT HAVE A CABIN FILTER. There are a lot of internet geniuses that says the 2009 Dodge 1500 has a cabin filter but it does not. I was fooled so I know. You can buy a kit and cut out a hole and install one but it does not come with a cabin filter.
