The 2008 Honda CR-V has two air filters: the engine air filter located in the engine bay and the cabin air filter located behind the glove box on the passenger side. Replacing both helps maintain engine performance and interior air quality.
Engine air filter location
To replace the engine air filter, locate the housing in the engine bay and follow these steps.
- With the engine cool, open the hood and find the rectangular black plastic air filter housing, usually toward the front of the engine bay on the passenger side.
- Unclip or unbolt the housing cover. Some models use two metal clips; others have a few screws. Remove the cover carefully.
- Take out the old filter and note its orientation. Clean any loose dirt from the housing using a rag if needed.
- Insert the new filter in the same orientation as the old one, ensuring the seal is seated evenly in the housing.
- Reattach the housing cover and secure the clips or screws firmly. Close the hood.
Once the engine air filter is replaced, the intake system should be sealed properly and the housing secured to prevent unfiltered air from entering the engine.
Cabin air filter location
To replace the cabin air filter, access the filter housing behind the glove box on the passenger side and follow these steps.
- Park the car, turn off the engine, and open the glove box. Remove any contents and, if present, detach the glove box damper or stop by squeezing the sides to allow the box to drop down.
- Look for a rectangular cabin air filter housing cover inside the glove box area. Release the clips or remove the screws holding the cover, then lift it off.
- Remove the old cabin filter and wipe the housing interior if dirt or debris is present.
- Insert the new filter with the arrows showing the correct airflow direction (usually toward the rear of the vehicle). Ensure the filter sits flat and fully seated in the housing.
- Replace the housing cover and reattach any clips or screws. Raise the glove box back into place and secure it.
After replacing the cabin filter, test the HVAC system to confirm airflow is normal and that there are no unusual noises from the housing area.
Summary
In a 2008 Honda CR-V, the engine air filter sits in a rectangular housing in the engine bay, while the cabin air filter is hidden behind the glove box on the passenger side. Both filters are user-serviceable with basic tools and straightforward steps: open the appropriate access, remove the old filter, insert a new one with the correct orientation, and resecure everything. Always consult your owner's manual for model-specific details and recommended replacement intervals based on driving conditions.
