Two air filters—an engine air filter and a cabin air filter.
In the 2013 F-150 lineup, the standard two-filter setup applies across most gas-engine configurations, including the 3.7L V6, 5.0L V8, and the 3.5L EcoBoost. This explainer outlines where those filters live and how to replace them.
Where to find them
Here is a quick breakdown of the two filters and their usual locations in the 2013 F-150.
Engine air filter
The engine air filter sits in the air intake housing in the engine bay, typically on the passenger side. To replace it: unclip or unfasten the housing cover, remove the old filter, insert a new one with the orientation arrows facing the engine, and reseal the housing. No specialized tools are typically required for most trims.
- Engine air filter: located in the air intake box at the front/side of the engine bay; replace by opening the housing and sliding a fresh filter in with the correct orientation.
Regular inspection is recommended, especially in dusty or off-road conditions, and replacement should follow the schedule in the owner's manual or sooner if you notice reduced performance or unusual engine noise.
Cabin air filter
The cabin air filter sits behind the glove box on the passenger side. Access is typically gained by opening the glove box and dropping down a panel or door; pull out the old filter and insert a new one with the airflow arrows pointing toward the heater core, then reassemble the glove box.
- Cabin air filter: located behind the glove box on the passenger side; remove the glove box or panel to reach the filter, replace, and reattach.
Replacing the cabin filter helps maintain interior air quality and HVAC efficiency. Depending on driving conditions, Ford generally recommends inspection every 15,000 miles and replacement around 15,000–30,000 miles, or per the owner's manual.
Maintenance notes
Keep in mind that some early or specialized trims could vary; always verify with the owner's manual or a Ford dealer if you're unsure. Using OEM or high-quality aftermarket filters is advisable for best results.
Summary
In short, a 2013 Ford F-150 typically has two air filters—an engine air filter and a cabin air filter. Knowing where they live and how to replace them can save time and help maintain engine performance and interior air quality.
