Replacing the engine air filter on a 2016 Honda Fit is a quick, do-it-yourself task that helps maintain engine performance and fuel efficiency. The job typically takes about 15 to 30 minutes and only requires a few basic tools and a new air filter.
In the 2016 Fit, the air filter sits inside a rectangular plastic housing in the engine bay, with the intake hose feeding air from the outside into the engine. The replacement involves opening the housing, swapping the dirty filter for a new one, and resealing the box. Always consult the owner’s manual for the exact interval and filter type recommended for your vehicle.
What you’ll need
Gather these items before you begin to ensure a smooth replacement.
- New engine air filter compatible with the 2016 Honda Fit (check the vehicle’s manual or parts retailer for the correct type)
- Flat-head screwdriver or small Phillips screwdriver (if required to release any clips)
- Clean rag or microfiber cloth
- Gloves (optional)
- Safety glasses (optional)
Having the right filter and basic tools on hand helps avoid delays and reduces the chance of damaging the housing.
Locating the air filter housing
The air filter housing is a rectangular black plastic box connected to a large intake hose. In the 1.5-liter engine bay, you’ll typically find it toward the side of the engine bay, with the air intake hose running into it. The lid is secured by clips or screws that must be released to access the filter.
Replacement steps
Follow these steps in sequence to replace the filter cleanly and safely.
- Park on a level surface, engage the parking brake, and turn off the engine. In cold weather, wait a minute for components to cool.
- Open the hood and locate the air filter housing. Inspect how the lid is attached—some models use clips, others use small screws or both.
- Release the clips or remove the screws. If needed, gently disconnect the intake hose from the box to gain better access. Do not force connectors.
- Lift the lid or top portion of the housing and remove the old air filter. Take note of its orientation and how it sits in the housing.
- Wipe the inside of the housing with a clean rag to remove dust or debris (do not leave loose debris inside).
- Insert the new filter, ensuring it sits snugly and in the same orientation as the old one. The cartridge should fill the housing completely without bending.
- Reattach the intake hose if it was removed, then reseat and secure the housing lid with the clips or screws. Ensure the clips are fully engaged or screws are snug.
- Close the hood and start the engine. Listen for unusual noises or unmetered air leaks. If you hear whistling or rough running, re-check the seal around the housing.
With the filter replaced, you’ll typically notice smoother idle and, over time, potential improvements in throttle response and fuel economy depending on driving conditions.
Filter orientation and compatibility
Most engine air filters are directional. Look for an arrow or "TOP" marking on the filter to align it with the housing. If you’re unsure, consult the filter packaging or the owner's manual. Use a filter that matches the 2016 Honda Fit’s engine (1.5L) specifications or the equivalent OEM/quality aftermarket part.
Aftercare and maintenance tips
Keep the area around the air box clean to prevent debris from entering the intake. It’s wise to inspect the air filter at every 12,000–15,000 miles (or as recommended by Honda) and replace roughly every 30,000 miles under normal conditions or sooner in dusty environments.
Summary
Replacing the engine air filter on a 2016 Honda Fit is a straightforward maintenance task that can improve engine efficiency and performance. With the right tools, a new filter, and a few careful steps, you can complete the job in under 30 minutes. Always refer to your owner’s manual for specific intervals and filter type, and consider having a professional do the job if you’re unsure about accessing the air box or re-sealing the housing properly.
