2020 Ford F-350-Super-Duty Air Filter in Lakewood, CO

The engine air filter sits in a rectangular airbox inside the engine bay, typically on the passenger side, ahead of the intake tube.

This housing opens with clips or screws so the filter can be inspected without special tools. On the 2020 Ford F-350 Super Duty, the airbox is designed for quick access, which helps during dusty Front Range driving. Our Lakewood team checks the seal and intake path during each service.

• Rectangular airbox in engine bay
• Opens via clips or screws for easy inspection
• Seal and intake path should be checked for debris

The cabin air filter is located behind the glove box, accessed by lowering the glove box and removing a small access panel.

This placement filters outside air before it enters the HVAC system, capturing dust, pollen, and roadside particulates common around Lakewood and Denver. Access usually requires releasing glove box stops and unclipping the cover.

• Behind glove box in HVAC intake path
• Access via glove box detents and panel cover
• Protects evaporator core and cabin air quality

The engine filter cleans air for combustion, while the cabin filter cleans air for passengers through the HVAC system.

Engine filtration helps maintain power, throttle response, and proper MAF readings. Cabin filtration maintains interior comfort, trapping dust and pollen—useful during Colorado’s spring and fall allergy seasons. Both should be inspected regularly, especially if you tow or drive on unpaved roads.

• Engine: protects intake, sensors, and cylinders
• Cabin: protects occupants and HVAC components
• Different locations, different media types

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

In the Denver metro’s dusty and sandy winter conditions, filters can load faster, making these symptoms more likely. If you notice sluggish acceleration or a blower that struggles to move air, it’s time to inspect both filters.

• Engine: hesitation, lower MPG, possible MAF contamination
• Cabin: diminished airflow, increased fogging, odors
• Visual: dark, debris-laden filter media

The engine filter is typically DIY-friendly, while the cabin filter may require trim removal; dealer service adds OEM specs and system checks.

Many owners can swap the engine filter using basic hand tools. The cabin filter sits behind the glove box and needs careful reassembly to avoid rattles. Larry H. Miller Ford Lakewood includes intake housing and MAF visual checks with OEM-spec filters for reliable fit and sealing.

• DIY engine filter: quick access in airbox
