In a 2011 CR-V, the engine air filter sits in a rectangular plastic box in the engine bay on the passenger side, while the cabin air filter is located behind the glove box in the dash. This article explains where they are and how to inspect or replace them.
Engine air filter location
The engine air filter protects the engine by filtering incoming air before it reaches the intake. The filter lives inside a large black plastic air box connected to a duct that runs toward the front of the car.
To locate and access the engine air filter, follow these steps:
- Park on a level surface, turn off the engine, and open the hood. Secure the hood.
- Locate the air intake box on the passenger side of the engine bay. It is a rectangular black plastic housing with a wide intake hose aimed toward the front of the vehicle.
- Unclip or unscrew the lid. Depending on trim, you may have several clips along the edge or a few screws; keep track of them.
- Remove the old filter element and note the correct orientation of the pleats for the new filter.
- Insert the new filter, reseat the lid, and secure the clips or screws firmly.
- Close the hood and run the engine briefly to check for normal operation.
Conclusion: Replacing the engine air filter is a routine maintenance task typically recommended every 30,000 miles, with more frequent checks in dusty or harsh environments.
Cabin air filter location
The cabin air filter sits behind the glove box on the passenger side of the dash. Access requires lowering or dropping the glove box area and removing a small access panel or cover that hides the filter.
Before attempting the cabin filter, prepare for glove box access and check the orientation arrows on the filter.
- With the glove box empty, gently squeeze the sides to release the stops and allow the glove box to drop down, or remove its damper if your model uses one.
- Look for a rectangular filter housing behind the glove box. Remove the housing cover by releasing tabs or screws.
- Slide out the old cabin filter; note its orientation and the airflow arrows.
- Insert the new cabin filter with the arrows pointing toward the cabin interior, reseal the housing, and reattach the glove box.
- Test the blower to ensure proper airflow and that nothing is loose.
Conclusion: Cabin air filter replacement is typically recommended every 15,000 to 25,000 miles, depending on driving conditions and allergy sensitivity.
Notes and tips
Variations can occur by trim level or regional production. If in doubt, consult the owner's manual or a certified technician for guidance on your specific vehicle.
Summary: The 2011 Honda CR-V has two air filters worth checking—an engine air filter housed in a passenger-side air box in the engine bay and a cabin air filter behind the glove box. Regular inspection and replacement help maintain engine performance and interior air quality.
