The engine air filter is housed inside a rectangular plastic box in the engine bay, typically connected to a large intake hose that runs from the front grille. The lid is held on by clips or screws and can be opened to replace the filter.
Where to look in the engine bay
To quickly identify the air filter housing, follow the main intake path from the grille into the engine compartment. The air box is a rectangular black plastic enclosure that receives air through a large diameter hose.
- Look for a large rectangular black plastic box with a removable top lid.
- Notice a thick intake hose that runs from the grille or front duct into the box.
- Check for a mass air flow (MAF) sensor mounted on the intake tube or near the box.
If you still can’t locate it, consult your owner’s manual or a generation-specific repair guide for your CR-V, as exact placement can vary by year and model.
How to inspect or replace the air filter
Use these steps to inspect and replace the air filter when needed. Ensure the engine is off and the hood is open, and have a replacement filter that matches your CR-V’s year and engine.
- Open the hood and locate the air filter housing by tracing the intake hose from the grille to the rectangular box.
- Unclip or unscrew the lid and lift it away from the box.
- Remove the old filter and inspect the inside of the housing for debris; wipe clean if necessary.
- Install the new filter with the orientation arrow (if present) pointing toward the engine, then reseal the housing and secure the lid with clips or screws.
- Reconnect the intake hose and start the engine to ensure there are no unsealed gaps or odd sounds.
Note: Replace the filter at the interval recommended in your owner’s manual, which is typically every 15,000–30,000 miles depending on driving conditions and environment.
Model-year variations
General guidance by CR-V generation
The basic setup—an air filter housing in the engine bay connected to a large intake hose—applies across CR-V generations. The exact side of the bay and mounting can vary by year and trim. For precise location and service instructions, refer to the specific owner’s manual or a generation-specific repair guide for your CR-V.
Summary
In short, the engine air filter in a Honda CR-V lives inside a rectangular air filter housing in the engine bay, connected to a large intake hose from the grille. You access it by releasing the housing lid with the appropriate clips or screws, replace the filter with the correct orientation, and resecure the lid. Always verify the exact location and replacement interval for your model year using the owner’s manual or a trusted repair guide.
