The 2018 Honda Accord Sport has two air filters you may need to check or replace: the engine air filter in the engine bay and the cabin air filter behind the glove box. The engine filter sits in a rectangular plastic housing on the passenger side of the engine compartment, while the cabin filter is tucked behind the glove box on the passenger side. The following guide walks you through locating and replacing both filters and offers practical maintenance tips.
Engine air filter location
To locate and replace the engine air filter, you’ll be working in the engine bay. The filter is contained in a rectangular air-filter box that feeds the throttle body, typically on the passenger side of the engine compartment. Access is usually gained by releasing a few clips or screws on the lid, then lifting the cover to remove the old filter.
What you’ll need
Replacement engine air filter, basic hand tools if clips or screws require it, and a clean rag to wipe away any debris inside the housing.
- Park the car on a level surface and turn the engine off. Let the engine cool if it has been running.
- Open the hood and locate the rectangular air-filter housing on the passenger side of the engine bay, near the fender and connected to a large intake hose.
- Unclip or unfasten the lid of the air-filter housing. Some models use quick-release clips; others may use small screws or bolts.
- Carefully lift the lid and remove the old engine air filter. Note the orientation of the filter as you remove it.
- Inspect the inside of the housing for debris. Wipe it clean with a rag if needed before installing the new filter.
- Insert the new engine air filter with the arrows on the filter pointing toward the throttle body (direction of airflow). Ensure it sits flat and fully seated in the housing.
- Reattach the housing lid and secure the clips or screws firmly.
- Close the hood and start the engine to verify there are no vacuum leaks or unusual sounds.
Replacing the engine air filter is a routine maintenance task that helps the Accord run smoothly and efficiently, especially in dusty conditions.
Cabin air filter location
The cabin air filter cleans outside air before it enters the HVAC system. In the 2018 Accord Sport, this filter lives behind the glove box on the passenger side. Access typically involves lowering or removing the glove box to reveal a small panel or housing containing the filter.
What you’ll need
Replacement cabin air filter, optional small flat-head screwdriver if your glove box has stoppers or damper pins, and a clean cloth to wipe dust from the area.
- Open the glove box and remove contents. Some models require removing a damper or side stops to drop the glove box down.
- Gently lower the glove box until you can see the cabin-filter access panel behind it.
- Remove the filter cover by sliding or popping out the retaining tabs or screws, depending on your trim.
- Take out the old cabin air filter. Inspect the filter for heavy dust and debris; replace if needed.
- Insert the new cabin air filter with the airflow arrows pointing in the direction of the blower motor (generally toward the interior of the car). Ensure it sits evenly in the housing.
- Reinstall the cover, secure the tabs, and lift the glove box back into place. Reinsert its contents.
- Test the HVAC by running the system to confirm proper airflow and a clean smell.
Regular cabin air-filter maintenance helps preserve interior air quality and HVAC efficiency, especially for drivers with allergies or in urban environments.
Summary
In the 2018 Honda Accord Sport, the engine air filter sits in a rectangular housing in the engine bay on the passenger side, while the cabin air filter is located behind the glove box on the same side. Accessing each filter involves simple steps: unclip or unlatch the housing for the engine air filter, or lower the glove box to reach the cabin filter. Replacement filters should be installed with the correct orientation, and the housings re-secured. Check the owner’s manual for exact instructions and recommended replacement intervals for your driving conditions.
