2020 RAM 3500 Air Filter in Millbury, MA

The 2020 Ram 3500 engine air filter sits inside the airbox in the engine bay, typically along the fender side for easy access.

This airbox feeds clean air to the 6.4L V8 intake to protect combustion and performance. During service in Millbury, our technicians release the airbox clips, remove the old element, and inspect the housing seal. For cabin filtration, many late-model Ram trucks position the cabin filter behind or beneath the glove box area.

• Engine air filter: airbox in the engine compartment
• Airbox opened by clips or screws for element access
• Cabin filter: typically behind/below the glove box on late-model Rams

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

The engine filter safeguards power and efficiency by keeping dust out of the throttle body and intake tract. The cabin filter traps pollen and fine particles before air reaches the vents. Both are serviceable items on a 2020 Ram 3500, and we install Mopar-spec filters at our Millbury facility.

• Engine filter: performance and engine protection
• Cabin filter: interior air quality and HVAC performance
• Both are periodic maintenance items with simple access points

Three common signs are reduced power, lower fuel economy, and a rough idle for the engine; plus weak airflow or musty odors from the cabin vents.

On a 2020 Ram 3500, a dirty engine filter can limit airflow to the 6.4L V8 and upset the air/fuel balance. A clogged cabin filter restricts HVAC flow and can carry odor-causing contaminants. Our Millbury team can inspect both filters during a single visit.

• Engine: sluggish acceleration and possible throttle response lag
• Engine: unexpected MPG drop on your usual Millbury/Worcester routes
• Cabin: reduced fan output or persistent dusty/musty smell

Yes the engine filter is typically DIY-friendly, while dealer service ensures OEM-spec parts and a full intake/HVAC check.

Many owners can access the engine airbox and swap the element using basic tools. The cabin filter may require glove box removal and careful handling of trim pieces. At Herb Chambers Chrysler Dodge Jeep RAM FIAT of Millbury, we use Mopar filters and check sealing surfaces to prevent unfiltered air bypass.
