2020 Ram Promaster Window Van Air Filter in Millbury, MA

The engine air filter sits in the engine bay inside a rectangular intake airbox on the driver’s side.

This 3.6L Pentastar V6 uses a sealed plastic airbox with quick-release clips or screws for access. When servicing at Herb Chambers Chrysler Dodge Jeep RAM FIAT of Millbury, our technicians also inspect the intake ducting and MAF/IAT sensor area for leaks or debris to protect performance and fuel economy. You can visually check the housing after popping the hood.

• Driver’s-side intake airbox with removable cover
• Upstream ducting checked for cracks or loose clamps
• Seal surfaces cleaned to prevent unfiltered air bypass

The cabin air filter is typically located behind the glove box in the HVAC intake, accessed through a service panel.

On many ProMaster vans, the cabin filter slides into a tray behind the glove box or low on the passenger-side dash. If your van is equipped, our Millbury team confirms placement and fitment, then replaces it with a Mopar-spec filter for proper airflow and filtration. This helps keep dust, pollen, and road odors from circulating inside your passenger area.

• Service panel access near glove box area
• Tray-orientation checked to ensure airflow direction is correct
• HVAC door operation verified after install

The engine filter cleans air for the 3.6L V6’s combustion, while the cabin filter cleans air entering the HVAC for you and your passengers.

Engine filters protect throttle bodies, sensors, and cylinders from abrasive dirt that can reduce power (280 hp) and increase wear. Cabin filters focus on comfort—trapping dust, pollen, and debris before it reaches vents. Both filters affect daily drivability in Central MA, especially during pollen seasons and on salted winter roads.

• Engine: performance and efficiency protection
• Cabin: interior air quality and HVAC airflow
• Different locations, different service procedures

Common signs include reduced power, lower fuel economy, and a rougher idle.

On the 3.6L V6, restricted intake airflow can blunt throttle response and increase fuel consumption. In Worcester County’s mixed driving—city idling, highway climbs, and dusty job sites—filters load faster. Our Millbury service team checks the filter media, airbox seals, and intake path to ensure clean, measured airflow to the engine.

• Sluggish acceleration, especially under load or towing
• Noticeable drop in MPG over several tanks
• Dark, debris-laden filter media on inspection

Typical signs include weak HVAC airflow, persistent window fogging, and musty odors from the vents.

A saturated cabin filter reduces the blower’s effectiveness and allows moisture and odors to linger. In Central Massachusetts, spring pollen and winter grit can load filters quickly. We’ll verify airflow, replace the filter if equipped, and confirm that the HVAC doors and seals function correctly for consistent defrost and cabin comfort.

• Fan speed feels higher than airflow suggests
• Allergy symptoms increase when HVAC runs
• Filter media looks gray or coated with debris

Yes—engine filters are usually DIY-friendly, while cabin filters may require trim panel access and careful alignment.

Many owners can open the engine airbox and swap the element. Cabin filters (if equipped) can be trickier due to panel fasteners and airflow orientation. Dealer service in Millbury adds OEM-spec parts, an intake/MAF visual, and a seal check to prevent unfiltered air bypass. You can schedule service or reference your owner’s manual for DIY steps.

• DIY: engine airbox clips/screws and correct filter seating
• Dealer: Mopar filter fit, seal integrity, debris removal
• Cabin: access panel handling to avoid damage

Yes—our Millbury service center installs genuine Mopar OEM filters for Ram vehicles.
