Two air filters — one engine air filter and one cabin air filter. Some model years or trims may vary, so consult the owner's manual for your specific vehicle.
Two filters, two jobs
The Ford Explorer relies on two primary air filters to support both performance and comfort. The engine air filter keeps dirt and debris out of the intake, helping with engine efficiency and longevity. The cabin air filter cleans the air that enters the passenger compartment, improving interior air quality. While two filters are standard, exact placement and access can vary by year and trim level.
Engine air filter
Location and purpose
The engine air filter is housed in a plastic box in the engine bay. The cover is usually secured with clips or screws and designed for quick access, so drivers can inspect or replace the filter without special tools. This filter protects the engine from dust and debris that can reduce performance and efficiency.
To replace the engine air filter, follow these steps:
- Park the vehicle, set the parking brake, and open the hood to locate the engine air filter housing near the front of the engine bay.
- Release the clips or remove the screws securing the housing lid to expose the old filter.
- Remove the old filter and inspect the inside of the housing for debris.
- Insert a new filter, aligning it with the housing orientation and any airflow markers or arrows.
- Reattach the housing lid and secure the clips or screws firmly.
- Close the hood and start the engine to verify normal operation and no unusual sounds.
After completing the replacement, ensure the housing is sealed properly to prevent unfiltered air from entering the intake and tidy up any tools used.
Cabin air filter
Location and purpose
The cabin air filter is typically located behind the glove box or beneath the dashboard, depending on the year and trim. It filters dust, pollen and other particulates from entering the passenger compartment, contributing to cleaner air inside the vehicle.
To replace the cabin air filter, follow these steps:
- Open the glove box and, if applicable, detach the damper or remove panels to access the cabin filter cover.
- Locate and remove the cabin filter cover from the HVAC housing.
- Remove the old filter and inspect the area for debris.
- Insert a new filter with the correct orientation, ensuring the airflow arrows point in the direction of airflow into the cabin.
- Replace the cover and reassemble the glove box or panels.
- Turn on the HVAC system to verify normal airflow and that there are no unusual noises.
After replacement, reset any cabin air filter indicator if your model supports it and confirm that the system is functioning properly.
Maintenance intervals
Recommended replacement intervals vary by model year and driving conditions. A common guideline is about 30,000 miles for the engine air filter and 15,000–30,000 miles for the cabin air filter, with more frequent changes in dusty or urban environments. Always check the owner’s manual for year- and trim-specific guidance and consider consulting a dealer or mechanic if you drive in harsh conditions.
Summary
In the current Ford Explorer lineup, you typically have two air filters: one for the engine and one for the cabin. Properly maintaining both filters helps preserve engine performance, fuel efficiency and interior air quality. For precise locations, replacement intervals, and steps tailored to your year and trim, refer to the owner’s manual or contact a Ford service professional.
