The 2013 Honda Accord uses two air filters: one engine air filter and one cabin air filter.
What filters are in a 2013 Honda Accord?
Two filtration components keep the engine clean and the cabin air fresh, and each has a distinct location and replacement procedure.
- Engine air filter — located in the engine compartment inside the air intake box. It protects the engine by filtering incoming air before it mixes with fuel.
- Cabin air filter — located behind the glove box and filters air entering the passenger compartment.
In short, the Accord relies on two filters, each serving a different system: the engine's air intake and the cabin's ventilation.
Where to find and replace them
Access for each filter varies: the engine filter sits in the intake box on the engine side, while the cabin filter is accessed through the glove box area.
- Engine air filter replacement steps (overview): open the engine intake box cover, unclip or unbolt the cover, remove the old filter, clean the box if needed, insert a new filter with the correct orientation, reseal the box, and reconnect components.
- Cabin air filter replacement steps (overview): remove or hinge down the glove box or access panel, slide out the old filter from its housing, insert a new filter with the correct direction arrows, reattach the housing and glove box.
Whether you replace one or both filters, following the correct steps keeps the system sealed and functioning properly.
Maintenance intervals and tips
Maintenance intervals vary with driving conditions. Here are typical guidelines for a 2013 Accord:
- Engine air filter: replace approximately every 30,000 miles under normal driving; replace sooner if you drive in dusty, sandy, or harsh environments.
- Cabin air filter: replace approximately every 15,000 miles or 12 months; replace more often in heavy urban traffic, dusty areas, or if you notice reduced airflow, odors, or pollen exposure.
Always verify with your owner's manual or a dealer for the exact intervals for your specific engine and trim, and consider inspecting filters annually if you drive in challenging conditions.
Part numbers and compatibility
Part numbers can vary by engine type and trim. To ensure the correct filter, check your 2013 Accord's VIN, consult the owner's manual, or use a trusted parts retailer's lookup. OEM Honda filters are typically preferred for fit and performance, while reputable aftermarket options are also widely used.
Summary
In the 2013 Honda Accord, two air filters are required: one engine air filter and one cabin air filter. Regular checks and replacements at the appropriate intervals help maintain engine performance and cabin air quality.
