To change the engine air filter on a 2017 Honda Fit, locate the rectangular air-filter housing in the engine bay (typically on the passenger side), open the clips or screws, swap in a new element, and reseal the housing. It’s a quick, straightforward maintenance task that can help maintain engine efficiency and performance.
Where the engine air filter lives and what to replace
The engine air filter sits inside a rectangular plastic housing in the engine compartment, usually on the passenger side near the edge of the engine bay. It connects to the intake duct that leads to the throttle body. The cabin air filter, by contrast, lives behind the glove box and is not involved in this process. You will replace only the engine air filter unless you’re performing a cabin filter change as well.
Tools and parts you’ll need before you begin:
- Replacement engine air filter compatible with the 2017 Honda Fit (OEM or equivalent)
- Flat-head or Phillips screwdriver, if your housing uses screws
- Gloves and a clean rag for wiping dust
- Optional: small pliers or a socket driver for any clamps
Having these ready helps the replacement go smoothly and minimizes the chance of recontaminating the intake.
Step-by-step replacement procedure
- Park on a level surface, turn off the engine, and engage the parking brake. Allow the engine to cool if it’s warm.
- Open the hood and locate the engine air filter housing on the passenger side of the engine bay. The housing is a rectangular box with an air duct connected to it.
- Release the clips or remove the screws that secure the housing cover. Some models use simple plastic clips; others may use small screws along the edge.
- Carefully lift the cover and remove the old air filter. Note the correct orientation of the filter so you can install the new one the same way.
- Inspect the inside of the housing for debris. Wipe away dust or leaves with a clean rag, taking care not to push debris into the duct.
- Insert the new air filter in the same orientation as the old one. Ensure it sits flat and fully covers the bottom of the housing with no gaps.
- Replace the housing cover and secure it with the clips or screws. Reattach any hoses or clamps you may have loosened.
- Double-check that all fasteners are tight and that the intake duct is properly connected and seated.
- Start the engine and listen for unusual sounds. If you hear a whistling or sucking noise, recheck the housing to ensure a proper seal around the filter.
- Dispose of the old filter according to local guidelines and store the new filter in its packaging until you’re ready to use it again.
Replacing the engine air filter should be part of routine maintenance. In general, Honda recommends checking the air filter at intervals noted in the owner's manual, which often fall around 15,000–30,000 miles, depending on driving conditions. If you drive in dusty or harsh environments, you may need to replace it more frequently.
Tips for a smooth replacement
Orientation and fit
Always install the new filter in the same orientation as the old one. An ill-fitting filter can cause poor sealing and allow unfiltered air into the engine, potentially reducing performance and increasing fuel consumption.
When to seek help
If you encounter damaged clips, a cracked housing, or trouble removing the old filter, consult a professional mechanic. A damaged seal can let dust into the intake and negate the benefits of a new filter.
Summary
The 2017 Honda Fit engine air filter is easy to replace: locate the housing on the passenger side of the engine bay, open it, remove the old filter, install a new filter with the correct orientation, and reseal the housing. Gather the right tools, set aside about 10–15 minutes, and recycle the old filter. Regular replacement helps maintain engine performance and efficiency, especially in dusty driving conditions.
