2020 RAM Promaster-Cargo-Van Air Filter in Denver, CO

The engine air filter sits in the engine bay inside a rectangular airbox connected to the intake tube.

You can access the housing by opening the hood and locating the airbox near the front or side of the bay, secured by clips or screws. The cabin air filter is separate and typically mounted behind the glove box, filtering HVAC air for the passenger area. For quick access and correct fitment, our Denver service team can confirm housing style and replace both filters with OEM parts.

The engine air filter protects the V6 intake for combustion, while the cabin air filter cleans the HVAC air you breathe.

The engine filter helps your 3.6L V6 maintain airflow for power and fuel efficiency by capturing dust and debris before the throttle body/MAF area. The cabin filter traps pollen and particulates entering the HVAC system to improve in-cabin air quality. Both are serviceable items and benefit from OEM-spec materials for correct flow and fit.

• Engine filter: performance and efficiency
• Cabin filter: occupant comfort and health
• OEM filters help preserve designed airflow

Common signs include reduced power, lower fuel economy, and a rougher idle for the engine; weak HVAC airflow or musty odors for the cabin.

If your van feels sluggish or down on power, the engine filter may be restricting intake airflow to the 3.6L V6. Inside the cabin, diminished blower output, dust on vents, or persistent smells point to a saturated cabin element. Our Denver technicians inspect both filters and related ducts to confirm the cause and restore proper flow.

• Engine: hesitation, worse MPG, uneven idle
• Cabin: weak airflow, odors, more dust on surfaces
• Quick inspections available with OEM replacements

The engine filter is often DIY-friendly, while the cabin filter may require trim removal; dealer service adds OEM parts and a full intake/HVAC check.

Many owners can open the engine airbox and swap the element with basic tools. Cabin filters may be behind the glove box with tabs or screws that are easy to damage if forced. At our Havana Street facility in Denver, we install Mopar-spec filters, inspect the intake ducting and MAF area, and dispose of the old elements responsibly.

• DIY: engine filter is typically straightforward
• Dealer: cabin access, fitment, and inspections
• Book online: schedule service

Follow the maintenance schedule in your owner’s manual for the engine air filter interval on your van.

Driving conditions can shorten intervals—frequent construction zones, unpaved routes, or heavy dust load the filter sooner. Our Denver advisors can inspect the element and document its condition to help you plan the next change. If the filter looks dirty or deformed, replacing it protects performance and fuel economy.

• Use owner’s manual interval as the baseline
• Inspect more often in dusty or high-mileage use
• Quick checks during routine maintenance visits

Use the owner’s manual maintenance schedule for the cabin air filter replacement interval.

Pollen seasons, wildfire smoke, and urban dust can saturate the cabin element faster, reducing HVAC airflow and interior air quality. Our team can assess the filter and show you its condition so you can decide on replacement timing. If airflow drops or odors persist, a new OEM cabin filter typically restores performance.

• Owner’s manual = official interval source
• Replace sooner with persistent odors or weak airflow
• OEM filter helps maintain HVAC performance

OEM Mopar filters are engineered for proper fit and airflow, helping the V6 maintain power and the HVAC system maintain consistent ventilation.
