The air filter sits inside the engine air intake box in the engine bay. It’s accessible by removing the lid of a rectangular plastic air box that’s connected to the intake hose leading to the throttle body.
In this article, we outline where to look, what you’ll need, and how to replace the engine air filter on a 2020 Ram 1500. We’ll also cover maintenance tips so you know when to check or replace it and how to distinguish it from other filters in the vehicle.
Location at a glance
The engine air filter is housed in a rectangular black plastic box located in the engine compartment. The box is connected to a large intake hose that runs toward the throttle body. Access is gained by releasing the fasteners or clips on the lid and lifting it away to reveal the filter.
What you’ll need
Before you start, gather the following items to ensure a smooth replacement.
- Replacement engine air filter correctly sized for the 2020 Ram 1500 (check your VIN/engine type: 3.6L V6 Pentastar or 5.7L Hemi).
- Tools or accessories for the fasteners (clips or screws) on the air box lid, if needed.
- Clean rag or paper towel to wipe the inside of the housing lip.
- Optional: flashlight to clearly see inside the air box.
With these items ready, you’ll be prepared to access and replace the filter without unnecessary delays.
Steps to locate and replace the air filter
Follow these steps to access and replace the engine air filter in your 2020 Ram 1500.
- Open the hood and locate the rectangular engine air box in the engine bay, connected to the large intake hose.
- Unclip or unscrew the lid of the air box to open it. If your model uses clips, gently lift them; if it uses screws, remove them with the appropriate tool.
- Lift the lid and remove the old air filter, noting how it sits in the housing so you can install the new one the same way.
- Inspect the inside of the air box for any debris or leaves and wipe the inside edge with a clean rag to ensure a good seal.
- Insert the new air filter into the housing, making sure it seats evenly around all edges and aligns with any ridges or guides in the box.
- Reposition the air box lid and secure the clips or screws to seal the box snugly.
- Lower the hood and start the engine to check for normal idle and listen for any unusual air leaks around the box.
Regularly servicing the engine air filter helps maintain power, fuel efficiency, and engine longevity. If the filter looks very dirty or clogged, replace it promptly and dispose of the old filter according to local regulations.
Additional tips and maintenance
Cabin air filter and other filters
Remember that the cabin air filter is a separate component located inside the passenger compartment, typically behind the glove box. It protects the interior from dust and pollen, not the engine’s intake air.
When to replace
Engine air filters generally require replacement every 15,000–30,000 miles under normal conditions, but dusty or harsh environments can shorten that interval. Check your owner’s manual for the recommended interval for your specific engine and driving conditions, and inspect the filter if you notice reduced engine power, rough idling, or decreased fuel economy.
Summary
The 2020 Ram 1500’s engine air filter is housed inside a rectangular plastic air box in the engine bay, accessible by removing the box lid. Gather the replacement filter and any needed tools, open the box, swap in the new filter with correct orientation, reseal the box, and test the engine. Regular checks help keep your truck running smoothly and efficiently.
