The 2015 Honda Civic has two air filters: an engine air filter housed in a rectangular plastic box in the engine bay, and a cabin air filter located behind the glove box under the dash.
In this article, you’ll learn the exact locations of both filters, how to replace each one, and tips to keep them in good condition. We’ll cover practical steps that apply to typical 2015 Civics and note where the process may vary slightly by trim.
Engine air filter
Location in the engine bay
Locate the engine air filter housing, a rectangular black plastic box connected to the intake hose. It is typically situated in the engine bay on the side of the engine compartment, often toward the passenger side near the front of the vehicle. The exact position can vary by model and engine, but the housing will be clearly visible and held shut by clips or screws.
Below are the steps to locate and replace the engine air filter. This list emphasizes the common steps used across many 2015 Civics and similar models.
- With the hood open, identify the engine air filter housing—the large rectangular plastic box connected to the intake hose.
- Release the fasteners (clips or screws) that secure the housing lid. If there are screws, use the appropriate screwdriver; if there are clips, gently unclip them.
- Lift or remove the lid to access the filter inside. Take note of the orientation of the existing filter, paying attention to any arrows indicating airflow.
- Remove the old filter and compare it to a new one to ensure you have the correct size and orientation. If needed, clean out any loose debris from the housing.
- Insert the new engine air filter with the airflow arrow pointing toward the engine, reseal the housing, and secure it with the clips or screws.
Replacing the engine air filter helps ensure optimum engine performance and fuel efficiency. After replacement, double-check that the housing is fully closed and secure.
Cabin air filter
Location behind the glove box
The cabin air filter is located behind the glove box under the dashboard. Access typically involves lowering the glove box and locating a small cover or housing panel that contains the filter. Depending on the trim, you may need to remove a damper or panel to reach the filter.
Below are the steps to access and replace the cabin air filter. These steps reflect the common approach used on many 2015 Civics to keep interior air fresh and reduce odors.
- Carefully empty the glove box and support or disconnect the glove box damper if present to allow full access downward.
- Gently push the glove box inward or lower it until you can see the cabin filter cover or housing panel on the far side.
- Open the filter cover by unclipping or unscrewing the tabs, then pull out the old cabin air filter.
- Insert the new cabin air filter with the airflow direction arrows pointing in the correct direction (usually toward the blower). Ensure it sits flat and fully seated in the housing.
- Reattach the cover, secure any clips or screws, and restore the glove box to its original position, including the damper if removed.
A new cabin air filter helps improve interior air quality and can reduce odors, especially in dusty or urban environments. If you notice reduced airflow from the vents or persistent odors, consider replacing the cabin filter.
Maintenance tips and replacement frequency
Typical maintenance guidelines for a 2015 Honda Civic suggest the following, though you should check your owner’s manual for the exact recommendations for your trim and driving conditions.
- Engine air filter: inspect at every 15,000 miles (24,000 km) and replace around 30,000 miles (48,000 km) under normal conditions; more frequent changes may be needed in dusty or harsh climates.
- Cabin air filter: inspect and replace roughly every 15,000 miles (24,000 km) or about once per year, whichever comes first; replace sooner if you notice reduced airflow, smells, or allergy symptoms.
Regular checks help maintain engine efficiency and interior air quality. If you drive in heavy dust, construction zones, or frequent urban traffic, consider more frequent inspections and replacements.
Summary
For a 2015 Honda Civic, you’ll find two filters to manage intake and interior air: the engine air filter in a rectangular plastic housing in the engine bay (location varies slightly by model but is easy to spot near the intake tube), and the cabin air filter behind the glove box under the dash. Replacement is straightforward: open the housing or panel, replace the filter with the correct orientation, and resecure the cover or glove box. Following the recommended maintenance intervals helps maximize engine performance and interior air quality.
