The engine air filter is located inside a rectangular plastic housing in the engine bay on the passenger side.
In addition to the engine air filter, the Honda Fit also has a cabin air filter behind the glove box. This article focuses on locating and replacing the engine air filter in the engine bay, a routine maintenance task that helps protect the intake system and maintain performance.
Locating the engine air filter housing
Use the steps below to locate and access the engine air filter box safely.
- Open the hood and look toward the passenger side of the engine bay for a rectangular black plastic box, connected to a large duct that runs toward the throttle body.
- Follow the large intake hose from the air box to the throttle body to confirm you have the correct housing.
- Identify how the lid is secured—most Fits use plastic clips or small screws. Prepare a tool if screws are needed.
Once you have located the housing, you can move on to opening it and inspecting the filter inside.
Notes by model year
Most Honda Fits from recent generations use a clip- or screw-secured lid. If you see a metal clamp or several plastic tabs, follow the same general process to release the lid. Always make sure the engine is off and cool before handling components in the engine bay.
Proceed to open the lid and remove the old filter to inspect and replace as needed.
Replacing the engine air filter
Before starting the replacement, ensure you have the correct replacement filter model for your Honda Fit’s year and engine type. Prepare a clean workspace and avoid letting dirt fall into the air intake.
- With the lid released, lift it or swing it open to expose the filter element.
- Carefully remove the old filter, noting the orientation of the filter so you can install the new one the same way.
- Insert the new filter, making sure the arrows on the filter face toward the engine (the direction of airflow).
- Re-seat the lid and secure the clips or screws firmly, ensuring the housing is closed airtight.
A quick visual check after reassembly should show no gaps between the lid and housing, and the intake hose should be firmly connected. You do not need to reset any service lights after a standard air filter replacement.
Maintenance tips
Inspect the filter every 12,000 to 15,000 miles (or more often in dusty conditions) and replace as needed. Keep the surrounding area clean when removing or installing the filter to prevent dirt from entering the intake system.
Model variations and additional filter care
While the general location described above applies to most Honda Fits, a few years and trims may differ slightly in exact placement or clip style. If you have trouble locating the housing, consult the owner’s manual for your specific year and engine (1.5L). Some models also place an emphasis on replacing the air filter at regular service intervals rather than waiting for symptoms like reduced acceleration or unusual engine noise.
Summary
In a Honda Fit, the engine air filter lives in a rectangular plastic housing in the engine bay on the passenger side, beneath a lid secured by clips or screws. Access the box, remove the old filter, insert a new one with the airflow arrows toward the engine, and re-secure the lid. Regular replacement helps protect engine performance and fuel efficiency, while noting that the cabin air filter sits separately behind the glove box.
