The air filter you’re likely looking for is the engine air filter, which sits in a rectangular plastic housing in the engine bay on the driver’s side. The Ridgeline also has a separate cabin air filter located behind the glove box.
In this guide, you’ll find where each filter lives and how to access and replace them.
Engine air filter location
In the Ridgeline, the engine air filter is housed in a sturdy rectangular plastic box in the engine compartment, typically on the driver’s side near the front of the bay. A sizable intake hose leads from the air box to the throttle body.
To replace it, follow these steps:
- Open the hood and locate the large black rectangular air box on the driver’s side of the engine bay.
- Unclip or unscrew the fasteners securing the lid (these can be metal clips or plastic fasteners).
- Lift the lid and remove the old filter, noting the correct orientation for the new filter.
- Inspect the inside of the box; remove any debris you see with a clean cloth.
- Install the new filter in the same orientation as the old one, ensuring it sits flat.
- Re-seat the lid and secure the clips or screws firmly.
- Reconnect any hoses or clamps that were moved during removal.
- Close the hood and start the engine to verify normal operation (no whistling or misfires).
Standard replacement is typically every 30,000 miles, but refer to your owner’s manual for the exact interval and follow signs like reduced acceleration or increased engine noise as indicators to replace sooner.
Cabin air filter location
The cabin air filter is a separate filter that cleans the air entering the interior and is located behind the glove box. Access requires lowering the glove box and removing a small access panel or door.
To replace it, follow these steps:
- Open the glove box and remove contents to clear space.
- Gently press in on the sides of the glove box to release the stops and drop the box down.
- Find the cabin filter housing behind the glove box and remove the cover.
- Take out the old filter and inspect the housing for debris.
- Insert the new cabin filter with the correct orientation (arrows typically point toward the blower).
- Reattach the housing cover and lift the glove box back into place.
- Replace the contents of the glove box and close it.
Cabin filter replacement is generally recommended every 15,000–30,000 miles depending on driving conditions and climate.
