Replacing the air filter in a Kia Seltos is a straightforward maintenance task that typically covers both the engine air filter and the cabin air filter. With basic tools and a new filter, you can complete the job in about 15–30 minutes.
This article outlines how to locate and replace both filters on most Kia Seltos models, what you’ll need, and practical tips to ensure a proper fit and optimal airflow.
Engine air filter replacement
The following steps apply to the engine air filter, which protects the engine from dust and debris and helps maintain performance. Check your owner’s manual for the exact interval, but replacements are commonly recommended every 12,000–15,000 miles (19,000–24,000 km) or more frequently in dusty conditions.
Tools and materials you’ll need: a new engine air filter compatible with your Seltos, and basic hand tools. Most years require no special tools, though you may use a flat-head screwdriver if the clips are stiff.
- Open the hood and locate the engine air filter housing, a rectangular black plastic box usually near the front or side of the engine bay.
- Release the clips or remove the screws securing the housing cover, then lift the cover away to expose the old filter.
- Carefully remove the old filter, noting its orientation for correct placement of the new one.
- Wipe the inside of the housing with a clean rag to remove any dust. Do not use water or cleaners that could leave residues.
- Insert the new filter in the same orientation as the old one, ensuring it sits evenly and seats fully in the housing.
- Reinstall the housing cover and secure the clips or screws. Start the engine to verify there are no abnormal noises or air leaks.
Replacing the engine air filter helps maintain engine efficiency, power, and fuel economy, particularly in harsh or dusty environments.
Cabin air filter replacement
The cabin air filter cleans the air entering the vehicle’s interior through the HVAC system. Replacement frequency varies by environment and usage, but many owners replace it every 15,000–25,000 miles (24,000–40,000 km) or annually, with more frequent changes in dusty areas or heavy city driving.
Tools needed are minimal: a new cabin air filter compatible with the Seltos; in some trims you may need a screwdriver or simply a pass-through access behind the glove box.
- Inside the passenger-side footwell or behind the glove box, locate the glove box and open it fully.
- Gently release the glove box stops or hinges to lower the glove box and gain access to the filter cover behind it (the exact location can vary by year/model).
- Remove the filter cover by undoing the latch or removing screws, then take out the old cabin filter, observing the airflow direction indicated on the filter.
- Clean any debris from the filter housing, then insert the new filter with the arrows pointing in the direction of airflow (from outside the vehicle toward the cabin).
- Reattach the filter cover and close the glove box, ensuring any stops or hinges click back into place.
After installing the cabin filter, run the vehicle’s HVAC on a few minutes to confirm a steady airflow and to check for odors or unusual airflow sounds.
Summary
Regularly replacing both the engine and cabin air filters in your Kia Seltos helps protect the engine, maintain fuel efficiency, and improve interior air quality. Always refer to your owner’s manual for model-year specifics and follow the outlined steps to ensure a proper fit and seal.
