2020 RAM 1500-Classic Air Filter in Denver, CO

The engine air filter sits inside the under‑hood airbox on the driver’s side, ahead of the intake tube.

This location lets the 2020 Ram 1500 Classic draw filtered outside air before it reaches the throttle body. Access typically involves unclipping or unscrewing the airbox lid and lifting out the old element. Our Denver team checks the housing and seals for debris and proper fitment to avoid unmetered air leaks.

• Under-hood airbox with quick-access clips or screws
• Upstream of the mass airflow/intake tract
• Seal inspection helps prevent dirt bypass

The cabin air filter is typically positioned behind the glove box within the HVAC intake area.

On many Ram trucks, you’ll lower or remove the glove box to access a rectangular filter door. This filter cleans incoming air for you and your passengers, trapping dust and pollen common around Denver roadways. Our technicians replace it and verify blower operation and airflow direction.

• Access panel behind glove box area
• Filters HVAC intake air entering the cabin
• Airflow check after installation

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

On the 2020 Ram 1500 Classic, the engine element sits in the airbox to keep dirt from the intake tract and sensors. The cabin filter lives in the HVAC case to improve in-cabin air quality. Both matter—one safeguards performance, the other comfort and health.

• Engine: pre-throttle filtration for the 3.6L V6
• Cabin: traps dust, pollen, and debris for occupants
• Different locations, different materials

Common signs include reduced power, lower fuel economy, rough idle (engine), and weak HVAC airflow or musty odors (cabin).

If your 2020 Ram 1500 Classic feels sluggish or the HVAC struggles to push air, the filters may be loaded with debris. Colorado construction dust and seasonal pollen can accelerate clogging. Our Denver shop inspects filter media and the airbox to confirm condition before recommending replacement.

• Engine: hesitation, poor MPG, dark/dirty filter media
• Cabin: noisy fan, reduced vents airflow, odors
• Visual inspection verifies contamination

Yes—you can DIY the engine filter, but dealer service ensures OEM fitment plus intake and MAF checks.
