The 2019 Honda Civic uses two air filters: the engine air filter housed in the engine bay’s air intake box (on the passenger side) and the cabin air filter located behind the glove box on the passenger side. Both are replaceable with basic tools and a bit of care. This guide explains where to find them and how to swap them out.
Engine air filter location and access
The engine air filter sits inside a large black rectangular housing in the engine bay, near the front-right (passenger) side. It connects to a plastic intake tube that leads to the throttle body. Here’s how to locate and replace it:
- Open the hood and locate the air intake housing on the passenger side of the engine bay; it’s typically the largest box with an intake hose running toward the throttle body.
- Release the clips or screws securing the lid; most 2019 Civics use simple clips or small bolts.
- Lift the lid to expose the engine air filter; note the filter’s orientation for proper reinstall.
- Remove the old filter, inspect the housing for debris, wipe if needed, and insert a new filter in the same orientation.
- Replace the lid and secure the clips or bolts firmly; recheck that the intake hose is properly connected and not kinked.
Replacement intervals are generally in the range of about 15,000–30,000 miles under normal conditions, with more frequent changes possible in dusty or harsh environments. If you notice reduced performance or odd engine sounds, inspect the filter sooner.
Cabin air filter location and access
The cabin air filter is tucked behind the glove box on the passenger side of the vehicle. Accessing it requires opening the glove box and removing a panel or damper to reach the filter slot.
- Open the glove box and squeeze the sides to release the stops, allowing the box to drop down or remove the damper if present.
- Locate the rectangular access panel at the back or side of the glove box and remove it to reveal the cabin air filter.
- Slide out the old filter, noting the correct orientation for the replacement (airflow arrows are usually visible on the filter).
- Insert the new filter with the proper orientation, then reattach the access panel and restore the glove box to its normal position.
Cabin filter replacement is typically recommended every 12–24 months or about 15,000–30,000 miles, depending on driving conditions and environment. Dusty roads or urban pollution may require more frequent changes.
Additional notes and model variations
Across 2019 Civic trims, the general layout for the engine air filter and cabin air filter is similar, though small differences can occur between engine options (such as the 1.5L turbo and other configurations) or glove box designs. When in doubt, consult the owner’s manual or a Honda dealer for model-specific instructions.
Summary
In summary, the 2019 Honda Civic houses the engine air filter in the engine bay’s passenger-side air intake box and the cabin air filter behind the glove box on the same side. Both filters are accessible with basic tools and standard steps, and regular replacement helps maintain engine performance and interior air quality.
