The 2023 Honda Accord Hybrid Sport uses two main service filters: the engine air filter located in the engine bay and the cabin air filter located behind the glove box. There isn’t a user-serviceable fuel filter in this model; if you’re dealing with fuel-system concerns, consult a Honda dealer or your owner's manual for guidance.
Engine air filter
Location and access
Access the engine air filter by opening the hood and locating the air intake housing on the passenger side of the engine bay. The housing is a rectangular plastic box connected to intake ducts.
- With the engine off, unclip or unbolt the air box lid. Some models use simple clips; others may have small screws.
- Lift the lid and remove the used filter, noting the orientation of the filter and any markings showing airflow direction.
- Inspect the inside of the housing and the ductwork for debris such as leaves or dust; wipe lightly if needed.
- Insert the new filter, ensuring the airflow arrows on the filter face toward the engine. Refit the lid and re-secure the clips or screws.
- Close the hood and run the engine briefly to ensure there are no air leaks and that the intake is sealing properly.
Replacing the engine air filter at the recommended interval helps maintain throttle response, fuel economy and overall engine performance.
Cabin air filter
Location and access
The cabin air filter is located behind the glove box on the passenger side. Access is gained by dropping the glove box and opening the cabin filter cover.
Before removing the glove box, empty it and gently press on the sides to release the stops, or remove the damper if your vehicle has one, so the glove box drops down enough to expose the filter housing.
- Open the glove box fully and locate the access panel behind it; detach the panel to reveal the cabin filter housing.
- Unclip or unscrew the housing cover and pull out the old cabin filter. Check for any debris in the housing.
- Insert the new cabin filter with the arrows pointing in the direction of airflow (toward the cabin interior or as indicated on the filter).
- Reattach the housing cover and the glove box, ensuring the damper or stops engage correctly.
Regular replacement of the cabin air filter improves HVAC performance and helps reduce odors and allergens inside the vehicle.
Summary
The 2023 Honda Accord Hybrid Sport follows the same filter layout as other Honda Accords: engine air filter in the engine bay and cabin air filter behind the glove box. There is generally no routine consumer-serviceable fuel filter, but always consult the owner's manual or a dealer for model-specific guidance. Regular maintenance of both filters supports engine efficiency and cabin air quality.
