The 2010 Honda Accord uses a standard rectangular engine air filter (panel-type) housed in the engine’s air intake box. The exact part number varies by engine: the 2.4-liter four-cylinder and the 3.5-liter V6 (and the Hybrid variant) require different OEM filters. Identify your engine to buy the correct filter.
Engine options in the 2010 Accord
For model year 2010, the Accord was offered with two gasoline powertrains: a 2.4-liter inline-four and a 3.5-liter V6. There was also a hybrid variant that used a different powertrain but still employed a panel-type air filter in an identical air-box arrangement. The location and replacement process are similar, but the part number differs by engine. Use the engine code or VIN to confirm the exact filter required.
2.4-liter inline-four
The 2.4L four-cylinder model uses a standard rectangular engine air filter. Replacing it is a straightforward job that you can do at home with basic tools. Below are the typical steps to replace the air filter in this engine:
- Open the hood and locate the air intake box, usually on the side of the engine bay.
- Unclip or unlatch the cover and lift it off to expose the filter.
- Remove the old filter, noting the orientation for reinstalling the new one.
- Clean any debris from the air box and insert the new filter with the correct orientation.
- Secure the cover back in place and reconnect any clips or fasteners.
After you replace the filter, run the engine briefly to ensure there are no air leaks and that the clips are fully secured.
3.5-liter V6
The 3.5L V6 uses the same panel-type air filter in a larger air box. The replacement process is the same as for the 2.4L engine, with the same safety precautions and steps. If you’re unsure of the orientation, refer to the notch or arrow on the filter edge indicating airflow direction, then install accordingly.
- Open the hood and locate the air intake box (larger than the 2.4L box).
- Release the clips or screws holding the lid, lift off the cover, and remove the old filter.
- Inspect the housing for debris; wipe clean if necessary.
- Install the new filter in the correct orientation and reseal the box.
- Secure the lid with clips or screws and close the hood.
With the V6 model, ensure the air box is sealed properly to prevent unfiltered air from entering the intake tract.
Hybrid version considerations
The 2010 Accord Hybrid uses a similar panel air filter in a comparable box, but some hybrid models have slightly different routing. The replacement steps are effectively the same as the gasoline models. Always verify the part number with your VIN or owner’s manual.
Where to buy and how to verify the right part
To ensure you purchase the correct filter for your exact engine, use one of these verification methods before buying:
- Check the engine type on your vehicle's data plate or owner's manual to determine whether you have a 2.4L, 3.5L, or hybrid powertrain.
- Remove the current air filter and read the OEM part number printed on the filter itself, if visible.
- Cross-reference part numbers at a Honda dealership, authorized parts retailer, or a reputable auto parts website using your VIN.
Most aftermarket panels such as Fram, Bosch, or ACDelco offer compatible replacements, but ensure the filter matches the exact dimensions and airflow rating for your engine.
Summary
The 2010 Honda Accord uses a panel-type engine air filter, with the exact part number depending on the engine: 2.4L I4 or 3.5L V6 (and hybrid). The replacement procedure is the same basic process across variants: locate the air box, remove the old filter, insert the new one with proper orientation, and reseal the box. Always verify the correct part using your engine type, VIN, or the number printed on the current filter.
