The engine air filter sits inside a rectangular air-filter housing in the engine bay, typically on the passenger side (right side when facing the car). The lid is secured with clips or screws, and removing it provides access to the filter inside.
Where to look in the engine bay
The Buick Encore’s air-filter box is a black plastic enclosure that sits toward the front of the engine compartment on the passenger side. A large intake hose from the grille connects to the box, and the filter is protected by a removable lid.
Model-year considerations
Across common Buick Encore models (such as the 2013–2019 lineup with the 1.4L turbo), the basic layout is the same: the air-filter housing is easily accessible without removing major components.
Replacing the air filter
To access and replace the filter, follow the steps below. This list is designed to be straightforward for most owners.
- Park the vehicle on a level surface, turn off the engine, and open the hood. Locate the rectangular air-filter housing on the passenger side of the engine bay.
- Inspect the housing to see how the lid is secured—clips or screws. Release the fasteners to lift the lid.
- Remove the old filter from the box and check for dirt, holes, or damage.
- Insert a new filter with the correct orientation (pleats facing the engine) and ensure it sits evenly in the housing.
- Reattach the lid and secure the clips or screws firmly. Reconnect any hoses if you loosened them.
After replacing, start the engine and listen for any unusual intake noise. Make sure the lid is fully seated and the hose is clamped securely.
Summary
The engine air filter on a Buick Encore is located in a rectangular housing in the engine bay, usually on the passenger side. Replacing it is a simple process of opening the lid, swapping in a new filter, and resecuring the lid. Regular replacement helps maintain engine performance and efficiency.
