2020 Ram 3500 Air Filter in Tucson, AZ

The engine air filter on a 2020 Ram 3500 sits inside the under-hood airbox on the passenger side, ahead of the 6.4L V8 intake tube.

This panel-style filter feeds the 410-hp 6.4L V8 and is easy to reach by unclipping the airbox cover. Keeping it clean helps maintain throttle response and fuel economy, especially in Tucson’s dusty conditions. Our technicians also check the airbox seals and intake ducting for leaks that can bypass filtration.

• Position: passenger-side engine bay airbox
• Access: release airbox clips, lift cover, slide filter out
• Tip: inspect for debris after off-road or construction-zone driving

The cabin air filter is typically behind the glove box in a 2020 Ram 3500, accessed by dropping the glove box and removing a small HVAC access panel.

This filter screens dust and pollen before air enters the HVAC system—important for Tucson’s desert environment. While DIY is possible, trim clips can be fragile; our team replaces the filter, checks blower operation, and ensures the access door seals properly to prevent bypass.

• Location: behind glove box, HVAC access door
• Tools: trim-safe approach; avoid forcing clips
• Add-on: ask for an evaporator intake inspection for odors

The engine air filter protects the 6.4L V8’s intake, while the cabin air filter cleans the air you breathe through the HVAC in the 2020 Ram 3500.

Engine filtration preserves power and efficiency by keeping dust out of the throttle body and cylinders. The cabin filter traps dust, pollen, and road debris to maintain airflow and interior air quality. Both matter in Tucson’s dusty seasons; engine filters impact performance, cabin filters impact comfort.

• Engine filter: under-hood airbox; performance/fuel-economy impact
• Cabin filter: behind glove box; HVAC airflow/odor control
• Use OEM MOPAR filters for correct fit and sealing

Common signs include reduced power, poorer fuel economy, and a rougher idle for the engine filter, plus weak airflow and musty odors for the cabin filter.

On a 410-hp 6.4L V8, restricted intake can dull acceleration and towing response. Inside the cab, Tucson dust can quickly load the cabin filter, causing noisy fans and uneven vent output. Addressing these symptoms early helps protect both the engine and HVAC components.

• Engine: sluggish throttle, higher fuel use, intake whistling
• Cabin: decreased blower airflow, odors, hazy windows
• Visual: dark, debris-laden filter media

The engine filter is generally DIY-friendly, while the cabin filter can require trim handling—dealer service adds OEM-spec parts and system inspections.

Many owners can open the 2020 Ram 3500 airbox and slide in a new panel filter at home. At Larry H. Miller Dodge RAM FIAT Tucson, we install MOPAR filters, inspect the intake path and MAF area, and verify HVAC door sealing—details that help in high-dust Tucson driving.

• DIY: engine filter via airbox clips; no special tools
• Dealer: cabin access without damaging clips/panels
• Includes: fitment check, debris removal, proper disposal

Yes—our certified MOPAR technicians install genuine MOPAR-spec engine and cabin air filters on the 2020 Ram 3500.

The 2020 Ram 3500 here features a 6.4L V8 gas engine (engine code 8VNAG6.4) rated at 410 hp and 429 lb-ft.

That V-type, naturally aspirated setup uses a panel-style intake filter in the passenger-side airbox. Exact fitment ensures proper sealing and airflow at the 5600 rpm power peak and 4000 rpm torque peak. Our team matches the correct MOPAR filter to the VIN for accuracy.

• Displacement: 6417 cc (6.4L) V8, regular unleaded
• Induction: naturally aspirated (NA)
• Housing: passenger-side under-hood airbox, clip-on lid

Yes—restricted airflow can blunt the 410-hp 6.4L V8’s response, which you’ll feel when towing (the Ram 3500 is rated up to 33,700 lbs when properly equipped).

Under load, your engine needs clean, consistent intake flow. A clogged filter raises intake restriction, reducing power and increasing transmission downshifts and fuel use—especially on Tucson grades and in summer heat. Keeping the filter fresh preserves pulling confidence.

• Symptom: sluggish climbs, frequent downshifts
• Check: inspect filter before long-haul or desert trips
• Plan: book a pre-tow inspection via schedule service
