The engine air filter is housed in a rectangular black box in the engine bay, typically toward the front and connected to the intake tube. The cabin air filter sits behind the glove box inside the passenger compartment. These two filters serve different purposes and are replaced on different schedules.
In Hyundai Accent models, there are two filters that help keep air clean: the engine air filter cleans air entering the engine, improving performance and efficiency, while the cabin air filter cleans air entering the passenger compartment, helping with odors and allergens. This guide covers both locations and how to replace them on most common Accent configurations.
Engine air filter location
Follow these steps to locate and replace the engine air filter.
- Park the car on a flat surface, engage the parking brake, and turn off the engine.
- Open the hood and locate the engine air filter housing. It is a rectangular black box near the front of the engine bay, with a large intake hose attached.
- Unclip or unscrew the housing cover. Some models use plastic wing clips; others use small screws or bolts.
- Lift the cover and remove the old filter. Note the orientation of the pleats for correct reinstall.
- Inspect the inside of the housing for debris and wipe away any dust or leaves if present.
- Insert the new filter with the correct orientation, ensuring the filter seats evenly with the housing.
- Reattach the housing cover and secure it with the clips or screws you removed.
- Reconnect any hoses and close the hood. Start the engine and listen for a smooth intake sound.
Replacing the engine air filter is a straightforward maintenance task that helps maintain engine performance and fuel efficiency. Ensure the housing is sealed properly to prevent unfiltered air from entering the intake.
Cabin air filter location
These steps show how to replace the cabin air filter behind the glove box.
- Park the car, turn off the engine, and locate the glove box.
- Open the glove box and carefully release the mounting pins or push in the sides to allow the box to drop down. Some models use a damper that needs to be unhooked.
- Behind the glove box, locate the cabin air filter housing and remove the cover.
- Remove the old cabin air filter. Take note of its orientation for installing the new filter.
- Clean the housing if there is dust or debris, then insert the new filter, ensuring the airflow arrows point in the correct direction (usually toward the back of the car).
- Replace the cover on the filter housing and reassemble the glove box, ensuring it latches securely.
- Test the HVAC system by turning on the fan and verifying air flows normally from the vents.
Replacing the cabin air filter helps maintain interior air quality and cabin HVAC performance, especially in dusty or urban environments.
Maintenance tips and quick references
Regular replacement helps maintain air quality and system performance. The following guidelines are general references and can vary by model year; always check the owner's manual for your specific Hyundai Accent.
- Engine air filter: typically around 30,000 miles (48,000 km) or every 24–36 months, depending on driving conditions.
- Cabin air filter: typically around 15,000–30,000 miles (24,000–48,000 km) or every 12 months, depending on climate and usage.
- Look for signs that a filter needs replacement: reduced airflow, unusual odors, or increased HVAC noise.
When in doubt, replace filters sooner in dusty or heavy-traffic conditions, and have a professional inspect if you encounter fitment issues, leaks, or damaged housings.
Summary
In a Hyundai Accent, the engine air filter is inside a rectangular housing in the engine bay, while the cabin air filter is located behind the glove box. Replacing both filters is a practical, do-it-yourself maintenance task that helps protect engine performance and improve interior air quality. Refer to your owner’s manual for exact steps and intervals tailored to your model year.
