The air filter is housed in a rectangular black plastic box in the engine bay, typically on the passenger side, connected to a large intake hose that leads to the throttle body.
Locating the air filter housing in your Sentra
In most 2010 Sentra models, the air box sits toward the front of the engine compartment on the passenger side. It’s a rectangular container with a large intake hose attached, usually secured by clips or a few screws along the lid edge.
If you have trouble spotting it, follow the thick black intake hose that runs from the grille area toward the engine; the other end should plug into the air box.
How to replace the air filter
Below are the standard steps to swap in a new filter. Before starting, ensure the engine is off and the hood is safely propped.
- Locate the air filter housing on the passenger side of the engine bay and release the clips or screws that secure the lid.
- Remove the lid and take out the old air filter, noting its orientation (usually arrows pointing toward the engine).
- Inspect the inside of the housing for debris; wipe it clean if necessary.
- Insert the new filter into the housing, matching the orientation of the old one and ensuring a snug fit.
- Replace the lid and secure all clips or screws firmly.
- Reconnect any intake hose clamps you may have loosened, and close the hood.
- Start the engine and check for any unmetered air or unusual idle; a fresh filter should improve throttle response.
Regular replacement according to your owner’s manual keeps the engine breathing clean air; in dusty conditions you may need to replace more frequently.
Summary
The air filter on a 2010 Nissan Sentra resides in a rectangular black air box in the engine bay, usually on the passenger side near the front. To replace it, open the box, swap in a new filter with correct orientation, reseal the lid, and reconnect any hoses. Refer to the owner's manual for the exact replacement interval and ensure the housing is securely fastened after reassembly.
