The K&N Engineering VF8004 Heavy Duty Cabin Air Filter is designed for select 2020 and 2021 Freightliner Sprinter models. It replaces the stock cabin filter with a durable, reusable design that helps clean and freshen incoming air inside the vehicle cabin.
This cabin air filter helps capture most mold, mildew, fungus, spores, bacteria, and germs while helping control odors and contaminants during long drives. Its electrostatically charged filter media is designed to grab and hold dust particles, supporting cleaner cabin air.
The VF8004 is pre-treated and ready to install. When the filter becomes dirty, it can be cleaned and reused instead of replaced, helping provide a practical long-term filtration solution. K&N states that the filter comes with a 10-year or million-mile limited warranty.
This automotive cabin air filter fits 2020–2021 Freightliner Sprinter 2500 and 3500 applications listed by the manufacturer. K&N also identifies the 99-6000 Cabin Filter Cleaning Care Kit as an associated product for filter maintenance.
