The 2013 Hyundai Elantra has two air filters: the engine air filter in the engine bay and a cabin air filter behind the glove box.
Here’s where to locate each filter and how to replace them if needed, with practical, step-by-step instructions.
Engine air filter location
The engine air filter sits in a rectangular black plastic housing in the engine bay on the passenger side. The large intake hose runs from this box toward the throttle body, drawing air into the engine.
What you’ll need
Before you start, gather the tools and parts you’ll need to complete the job safely and efficiently.
- New engine air filter compatible with the 2013 Elantra
- Gloves and a clean rag (optional)
- Flat-head screwdriver or socket driver (if your housing uses screws or clamps)
Having these on hand helps you replace the filter quickly and with minimal disturbance to other components.
Replacement steps
Follow these steps to replace the engine air filter and restore optimal air flow to the engine.
- With the engine cool, open the hood and locate the engine air filter housing on the passenger side of the engine bay.
- Release the clips or remove the screws securing the housing cover, then lift off the cover.
- Take out the old filter and inspect the inside of the housing for debris; wipe clean if needed.
- Insert the new filter in the same orientation as the old one (the filter’s arrows should point toward the engine).
- Reinstall the housing cover and secure the clips or screws firmly.
- Close the hood and, if desired, reset any service indicator per your owner’s manual.
Replacing the engine air filter helps maintain fuel efficiency, performance, and engine longevity by ensuring clean air enters the intake system.
Cabin air filter location
The cabin air filter is located behind the glove box on the passenger side. Access is usually gained by lowering or removing the glove box and removing a small panel or cover that houses the filter.
What you’ll need
Prepare the following items to replace the cabin air filter with minimal hassle.
- New cabin air filter compatible with the 2013 Elantra
- Optional: flashlight for better visibility
- Clean cloth to wipe the housing interior
Ensure you have the right filter type (some models use a standard rectangular cabin filter) before starting.
Replacement steps
Use these steps to access and replace the cabin air filter.
- Open the glove box and inspect for any stoppers or damper arms; release them so the glove box can lower fully.
- Look for a small access panel or door behind the glove box; slide or unclip it to reveal the cabin air filter housing.
- Remove the old filter, noting the correct orientation (usually with an arrow indicating airflow).
- Wipe the housing gently with a clean cloth to remove dust and debris.
- Insert the new filter with the same orientation, then reseal the housing and reattach the panel.
- Raise the glove box back into place and ensure it operates smoothly.
Installing a fresh cabin air filter helps improve interior air quality and can reduce odors from the HVAC system.
