There are two air filters to consider on a 2013 Honda Civic: the engine air filter located in the engine bay, and the cabin air filter housed inside the vehicle. In many Civics, the engine air filter is in a rectangular plastic box in the engine compartment, while the cabin air filter sits behind the glove box in the cabin. This article explains where to find both and how to replace them.
Engine air filter location
The engine air filter lives inside a rectangular black plastic housing in the engine bay. On a 2013 Civic, you’ll typically find it on the driver’s side (left side) of the engine compartment, near the front, connected to a large-diameter intake hose that runs toward the throttle body. The housing is secured with metal clips or screws, and the filter inside is a flat rectangular panel to be replaced when dirty.
Replacement steps for the engine air filter
Follow these steps to locate, remove, and replace the engine air filter.
- Park the car, turn off the engine, and open the hood. Locate the rectangular air filter housing on the driver’s side of the engine bay, tied to the large intake hose.
- Release the housing fasteners (clips or screws) and lift the lid away from the box. Keep track of any seals or gaskets.
- Remove the old air filter and inspect the inside of the housing for debris. If dirty, wipe it clean with a clean cloth or compressed air (careful not to blow debris into the intake).
- Install a new filter with the proper orientation. The filter will have a specific shape to fit inside the box; ensure the grooves and seal sit snugly against the housing.
- Reposition the lid and secure the clips or screws. Reconnect any hoses or clamps to the intake if you moved them.
After replacement, start the engine to confirm there are no abnormal noises and that the intake system is resealed properly.
Cabin air filter location
The cabin air filter on a 2013 Civic is usually located behind the glove box on the passenger side of the dash. Access is gained by lowering the glove box and removing a small access panel or filter cover. The filter protects the interior from dust, pollen, and debris as air is drawn through the HVAC system.
Replacement steps for the cabin air filter
Before starting, note that some trims may require removing the glove box damper or other small clips. The following steps describe the common method used on many Civics.
- Open the glove box and clear its contents. If applicable, gently disconnect the glove box damper or hinge stops to allow the box to drop down.
- Look for a rectangular cover on the cabin side of the dash—remove or press the tabs to release it and expose the cabin filter.
- Slide out the old cabin filter and inspect for dirt buildup. If dirty, replace with a new filter that matches the correct size and orientation (airflow arrows typically point toward the interior of the car).
- Insert the new filter, ensuring it sits flat and oriented correctly. Reattach the filter cover, then restore the glove box and any damper or stops you removed.
Once finished, test the HVAC system to ensure unimpeded airflow and that the cabin filter is seated properly.
Summary
For a 2013 Honda Civic, check both filters: the engine air filter in the driver’s-side engine bay housing and the cabin air filter behind the glove box on the passenger side. Replacing either filter is a straightforward DIY task involving opening housings, removing old filters, and installing new ones with correct orientation. Always consult the owner’s manual for exact locations and filter part numbers specific to your trim and regional market.
