2021 Dodge Durango Air Filter

The engine air filter on the 2021 Dodge Durango sits in the engine bay inside the plastic airbox at the front of the 3.6L V6 intake system.

On the 2021 Dodge Durango with the 3.6L V6, the airbox is a rectangular housing toward the front of the engine compartment; it secures with clips or screws and contains the paper filter element. Local technicians at LHM Sandy Jeep inspect the housing, seals, and intake path for debris and proper fitment when replacing the element.

• Location: engine bay, front of vehicle near air intake
• Access: remove a few clips or screws on the airbox cover
• Included check: intake boot and intake sensor visual inspection

The cabin air filter on the 2021 Dodge Durango is located behind the glove box, inside the HVAC intake area.

Access typically requires lowering or releasing the glove box to reach the cabin filter housing. LHM Sandy Jeep technicians remove the glove box trim as needed to inspect the cabin filter for pollen, dust, and road debris, and they check the HVAC drain and blower access while replacing the element.

• Location: behind the glove box in the passenger compartment
• Service action: glove box removal and filter housing access
• Inspection: blower motor area and HVAC intake for blockages

The engine air filter protects the 3.6L V6 combustion system by filtering intake air; the cabin air filter protects passengers and the HVAC system by filtering outside air entering the cabin.

The engine filter prevents dust and particulates from reaching the intake and MAF, which preserves power and fuel economy; the cabin filter captures pollen, dust, and odors before they enter the passenger compartment. Technicians treat each filter as a separate service item and inspect related components (airbox seals for engine filter, HVAC drain for cabin filter).

• Engine filter: protects intake and engine sensors
• Cabin filter: protects passengers and HVAC evaporator/blower
• Replacement intervals and inspections are handled separately

On a 2021 Dodge Durango, engine-side symptoms include reduced acceleration and lower fuel economy versus the rated 19 city / 26 highway, while cabin-side symptoms include weak HVAC airflow and a musty or stale odor.

If the engine air filter is restricted, the Durango's 3.6L V6 can feel sluggish and may struggle under load or while towing (rated towing 6,200 lb). If the cabin filter is clogged, occupants may notice poor defogging performance or increased allergen circulation—common in dusty South Valley conditions.

• Engine: reduced throttle response, hesitant acceleration
• Cabin: reduced blower output, stale or musty smells
• Inspection: technicians check MAF sensor and intake path for debris

You can often replace the engine air filter yourself on a 2021 Dodge Durango with basic tools; the cabin filter replacement may require glove box removal and is moderately more involved.

DIY engine filter replacement is possible because the element is in an accessible airbox, but owners should verify proper sealing and inspect the intake and MAF sensor.

OEM replacement parts are available under the Mopar brand to match factory fit and filtration; proper sealing and housing orientation are critical for both elements. Common service callouts for the Durango include dust loading from regional roads and pollen accumulation during spring months, which can accelerate filter contamination compared with low-dust environments.
