2020 Ram 3500 Air Filter

The engine air filter sits inside the under-hood airbox, and the cabin air filter is typically behind the glove box.

On a 2020 Ram 3500 with the 6.4L V8, the airbox is mounted in the engine bay with clips or screws securing the lid; the cabin microfilter accesses from the passenger-side dash area. If you prefer professional service, our Tucson team can inspect and replace both during a single visit. Use schedule service to reserve your spot.

• Engine filter: under-hood airbox with a removable lid
• Cabin filter: accessed from the glove box area on most trims
• Address for service: 4220 E 22nd St, Tucson, AZ

The engine air filter protects the 6.4L V8 intake from dust and debris, while the cabin air filter cleans the HVAC air you breathe inside the truck.

The engine filter helps maintain power and fuel economy by keeping contaminants out of combustion. The cabin filter traps pollen, dust, and odors to improve in-cab comfort. Our OEM parts counter supplies Mopar filters designed to fit the 2020 Ram 3500 precisely.

• Engine filter: safeguards performance and MAF readings
• Cabin filter: improves airflow and reduces allergens
• OEM fit: Mopar-spec media and sealing surfaces

Typical signs include reduced power, lower fuel economy, or rough idle (engine), plus weak HVAC airflow or musty odors (cabin).

In Tucsons dusty conditions, the 2020 Ram 3500 can load filters faster, especially during wind and pollen seasons. If you notice laggy throttle response or your vents feel restricted, its time to inspect. Our technicians provide a complimentary multi-point inspection at every visit.

• Engine symptoms: hesitation, poorer mpg, uneven idle
• Cabin symptoms: weak fan output, stale or dusty smell
• Quick check available via schedule service

Yesthe engine filter is generally DIY-friendly, while dealer service adds OEM-spec parts, proper fitment, and intake/MAF checks.

Many owners can swap the engine filter using basic tools; the cabin filter may require trim removal and careful reassembly. Dealer installation at Larry H. Miller Dodge RAM FIAT Tucson helps ensure correct sealing, no debris bypass, and verification of the intake tract.
