In a 2019 Honda Fit, there are two air filters you may need to replace: the engine air filter in the engine bay on the passenger side, and the cabin air filter behind the glove box on the passenger side. Both are accessible with basic hand tools and careful handling.
Engine air filter location
Where to look
The engine air filter is housed in a rectangular black plastic box in the engine compartment on the passenger side. An intake duct runs from the front of the engine bay into this box, feeding air to the throttle body.
Tools and steps you’ll use to replace the engine air filter
- Replacement engine air filter (OEM or equivalent)
- Flat-head screwdriver (optional, for stubborn clips)
- Clean rag to wipe the housing interior
- Gloves (optional)
With the hood open, unclip or unbolt the air box cover, lift the lid, remove the old filter, and inspect the inside for debris. Install the new filter with the arrow on the filter pointing toward the engine (toward the throttle body), reseat the cover, and reclip or rebolt. Reconnect any hoses if you detached them.
Ensure the intake duct is securely connected and all clips are fully engaged before closing the hood.
Cabin air filter location
Where to access
The cabin air filter in the 2019 Honda Fit sits behind the glove box on the passenger side of the dashboard. Access is typically gained by lowering or removing the glove box to reveal a small filter housing and cover.
Tools and steps you’ll use to replace the cabin air filter
- Replacement cabin air filter (HVAC), OEM or equivalent
- Small screwdriver (optional, for fasteners)
Steps: Open the glove box, release the stops or dampers, and lower the glove box to expose the filter housing. Remove the cover, take out the old filter, insert the new filter with the airflow arrows pointing toward the passenger side vent, reseal the housing, and reassemble the glove box.
Test the HVAC system after reassembly to confirm normal airflow and no unusual odors. Replace the cabin filter sooner in dusty or polluted environments.
Summary
For a 2019 Honda Fit, there are two filters to monitor: the engine air filter in the engine bay on the passenger side, and the cabin air filter behind the glove box. Replacement steps are straightforward and can be done with basic tools. Consult the owner's manual for exact replacement intervals and any model-specific nuances, and consider inspecting filters more frequently in dusty or high-pollution driving conditions.
