Upgrade your rig with a reusable K&N cabin air filter for 2020-2021 Freightliner Sprinter 3500 2.1L Diesel. Washable design captures dust, mold, and odors.

The K&N Heavy Duty Cabin Air Filter replaces your Sprinter's restrictive stock paper cabin filter with a premium, washable and reusable alternative. Specifically engineered for the 2020-2021 Freightliner Sprinter 3500 2.1L L4 Diesel, this filter refreshes incoming road air before it hits your vents.

Using an electrostatically charged non-woven synthetic media, it physically traps fine dust particles while capturing widespread environmental contaminants. Rather than tossing money away on disposable replacements every few thousand miles, this filter can be quickly cleaned, refreshed, and reinstalled for the lifetime of your commercial vehicle.
