The engine air filter is housed inside a rectangular black plastic box in the engine bay, typically located toward the front of the engine compartment on the side closest to the grille, and accessed by lifting the lid after releasing its clips or screws.
Understanding the exact spot helps you perform routine maintenance quickly. Honda often keeps the air box near the edge of the engine bay, connected to a large intake hose that delivers air to the throttle body. Variations between the 2.4L four-cylinder and the 3.5L V6, or between trims, exist, but the general principle remains the same: look for a square or rectangular air box with a prominent intake hose.
How to locate the air filter housing in the 2011 Accord
Use these cues to identify the air box and avoid removing the wrong component.
- Look for a large rectangular or square black plastic box in the engine bay, usually sitting near the front and connected to a thick air intake hose.
- Follow the thick hose from the grille/front of the car toward the center of the engine; the end that meets a box is the air filter housing.
- Check the housing lid, which is secured with clips or screws; releasing them reveals the filter inside.
- On some models, the air box may sit slightly toward the passenger side or driver’s side, but it will always connect to the intake hose that leads to the throttle body.
Once you’ve located the housing, you can proceed to inspect or replace the filter as needed.
Steps to replace the engine air filter
Replacing the air filter is a straightforward maintenance task. Follow these steps in order.
- Turn off the engine and open the hood. Let the engine cool if it’s warm.
- Release and remove the clips or screws securing the air box lid, then lift the lid off the box.
- Carefully lift out the old air filter, noting its orientation and how it sits in the housing.
- Inspect the inside of the housing for debris and wipe it clean with a damp cloth if needed. Do not use compressed air that could push dirt deeper into the intake.
- Insert a new air filter with the same orientation as the old one, ensuring the seal sits evenly around the edges.
- Reinstall the lid and secure all clips or screws firmly to seal the box.
- Reconnect any hoses or clamps you may have moved, and close the hood.
Ensure the air filter is properly seated and the housing is sealed to prevent unfiltered air from entering the engine. Dispose of the old filter according to local regulations.
Tips and cautions
Use the correct filter size for your 2011 Accord (check the owner's manual or parts diagrams if you’re unsure). If you’re replacing the filter yourself for the first time, you may want to have a flashlight handy to ensure you can see the inside of the box clearly before resealing it.
What to know if you’re unsure about your specific model
While the general location described above applies to most 2011 Accord models, there can be slight variations by engine type (2.4L vs. 3.5L) and market. If you can’t find the air box in the expected area, consult the owner’s manual or a service guide for your exact VIN and trim, or contact a Honda dealership for confirmation.

It is accessible by releasing the box’s clips or screws and lifting the lid. Replacing the filter is a quick, low-cost maintenance task that helps keep the engine drawing clean air and running efficiently.
