Two air filters protect the Civic’s performance: the engine air filter sits in a rectangular housing in the engine bay, while the cabin air filter sits behind the glove box. This guide explains exactly where to locate them and how to access them for inspection or replacement.
Engine air filter location
The engine air filter is housed in a rectangular plastic box in the engine bay. It is connected to the intake hose and secured with clips or occasional screws. Accessing the filter requires opening the lid of the box to expose the element.
- Open the hood and locate a rectangular black plastic air box near the front of the engine bay, typically on the passenger side or toward the center depending on your view.
- Release the clips or remove any screws holding the lid, then lift the lid to expose the filter inside.
- Remove the old filter, clean out any debris in the box, and inspect the housing for damage or tears in the filter housing.
- Insert a new filter with the correct orientation (the arrows on the filter should point toward the engine), reseat the lid, and secure the clips or screws.
With the lid secured back in place, close the hood. Replacing the engine air filter is a straightforward maintenance task that helps ensure the engine receives clean air for optimal performance.
Cabin air filter location
The cabin air filter is located behind the glove box. Access requires lowering the glove box and removing a cover to reach the filter housing.
- Open the glove box and gently press the sides inward to release the stops so the box can drop down.
- Remove the glove box damper and the cabin air filter access panel behind it to reveal the filter.
- Take out the old cabin filter, noting the airflow direction printed on the filter if present.
- Install a new cabin filter with the arrows pointing toward the blower motor, reseal the access cover, then reattach the glove box damper and reassemble the box.
After replacement, reassemble the glove box and test the HVAC system to ensure air is flowing properly and the cabin air smells fresh.
Maintenance notes
Choose filters that meet Honda specifications or an equivalent aftermarket part. If you’re unsure which part to buy, consult your owner’s manual or a dealership parts department. Always verify the filter is seated correctly and oriented for proper airflow.
Summary
The 2017 Honda Civic uses two filters: a engine air filter in a rectangular housing in the engine bay and a cabin air filter behind the glove box. Both are accessible with basic tools and straightforward steps: locate and remove the old element, install a new one with the correct orientation, and re-secure everything.
