The air filter in a 2016 Honda Fit sits inside the rectangular air-cleaner housing in the engine bay, typically on the passenger side. Access is gained by removing the housing lid and the filter element. This article explains exactly where to find it, how to replace it, and some maintenance tips.
Locating the air-filter housing in the engine bay
The air box is a large black plastic component connected to a wide intake hose that runs from the grille area toward the engine. In most 2016 Fits, you’ll find it on the passenger side of the engine bay, near the wheel well. The lid is secured with clips or small screws, and a mass airflow sensor may be attached to the intake tubing nearby.
What the air box looks like
Look for a rectangular, ribbed plastic box with an opening for a large flexible hose. The hose clamps onto the box and continues toward the throttle body.
Gather the tools and parts you’ll need before starting.
- New air filter element of the correct type (OEM or equivalent)
- Flat-head or Phillips screwdriver if your box uses screws; otherwise, you’ll only need your hands to release clips
- Clean microfiber cloth to wipe the interior
- Gloves to keep hands clean
Having the right parts and tools on hand will speed up the process and reduce the risk of dropping debris into the intake.
To proceed with the replacement, follow these steps.
- With the engine off and cooled, locate the air-filter housing and release the clips or screws securing the lid.
- Remove the lid and lift out the old filter, noting its orientation (the filter usually has arrows indicating airflow).
- Wipe the interior of the housing with a clean cloth to remove any dust or debris.
- Insert the new filter, ensuring it seats firmly and the arrows point in the direction of airflow toward the engine.
- Reinstall the housing lid and tighten the clips or screws securely. Reconnect any hoses if you had to disconnect them.
- Close the hood and start the engine to verify normal operation and no unusual noises.
Ensure the seal is snug and the housing is securely fastened to prevent unfiltered air from entering the intake.
Maintenance tips and replacement interval
Honda generally recommends inspecting the air filter at regular intervals and replacing it as dictated by the driving environment. In normal conditions, a replacement interval of about 30,000 to 60,000 miles is common, but dusty or harsh conditions may require more frequent changes. Always refer to the owner's manual for the official interval and any model-year variations.
Summary
The air filter on a 2016 Honda Fit lives inside the air-cleaner housing in the engine bay, most commonly on the passenger side. Replacing it is a straightforward task: remove the lid, swap in a new element, and reseal the box. With the correct filter and a few minutes, you can maintain proper engine performance and fuel efficiency. Always consult the owner's manual for the exact replacement interval and filter specifications for your trim.
