The air filter sits inside the rectangular engine air intake box in the engine bay, on the passenger side near the front of the car. It’s accessible by releasing the clips or screws on the lid and swapping in a new filter. When in doubt, consult the owner’s manual for the exact specifications for your model and engine.
For 2019 Impala models with either the 2.5L four-cylinder or the 3.6L V6, the air box occupies the same general area, and the replacement procedure is similar. This guide covers location details and how to replace the filter step by step.
Where to look in the 2019 Impala
Most versions share a common layout: a rectangular black plastic air box sits on the passenger side of the engine bay toward the front. A large duct runs from the air box to the throttle body mounted at the front or center of the engine. The lid is secured with plastic clips or small screws.
- 2.5L four-cylinder: air box is on the passenger side of the engine bay, near the front. A large intake hose leads from the box toward the throttle body at the center/front of the engine.
- 3.6L V6: air box is in the same general area on the passenger side; the intake duct connects to the throttle body at the front of the engine.
In all cases, ensure the air box seals properly when closed to prevent unfiltered air from entering the intake.
How to replace the air filter
What you’ll need and the general steps to replace the filter are outlined below.
- Park on a level surface with the engine off and cool. Open the hood and locate the air filter box on the passenger side of the engine bay.
- Unclip or remove the screws securing the lid, then lift the lid to expose the filter.
- Remove the old filter and inspect the housing for any debris. Wipe the inside of the box if needed to ensure a clean seal.
- Insert a new filter with the airflow arrows pointing toward the throttle body (into the engine). Make sure the filter sits evenly and that the box seals completely when you close the lid.
- Reattach the lid and secure the clips or screws. Start the engine and listen for any unusual noises that might indicate a loose seal.
Tip: Do not overtighten screws or clips, and double-check that there are no gaps between the lid and the box. If you drive in dusty conditions, you may need to replace the filter more frequently.
Maintenance tips
Frequency and indicators
Regular inspection helps preserve performance and fuel efficiency. Check the air filter every 12,000–15,000 miles (or as recommended in your owner’s manual). In dusty or harsh conditions, inspect and replace more often. Signs of a dirty filter include reduced acceleration, rough idling, and lower fuel economy.
Summary: On the 2019 Chevy Impala, the air filter is located in the engine’s rectangular air intake box on the passenger side of the engine bay, near the front. Replacement is straightforward and can be done with basic tools by removing the lid, swapping the filter, and resealing the box following the steps above.
Summary recap: The air filter in a 2019 Impala sits in the passenger-side air box in the engine bay. Access it by releasing the lid’s clips or screws, replace with orientation arrows toward the throttle body, and resecure the box. Regular checks help maintain performance and efficiency.
