2018 Ford F-350-Super-Duty Air Filter in Fort Worth, TX

The engine air filter sits inside a sealed airbox in the engine bay, while the cabin filter is typically accessed behind or near the glove box.

On the 2018 Ford F-350-Super-Duty, the intake snorkel routes outside air into a rectangular airbox that houses the engine filter. The cabin air filter helps clean HVAC air for passengers and is usually reached by removing the glove box or a trim panel. Our Fort Worth team can confirm locations and replace both using genuine Motorcraft filters.

• Engine filter: sealed airbox in the engine bay
• Cabin filter: generally behind/near glove box
• OEM fitment ensures proper sealing and airflow

The engine air filter protects the engines combustion air, while the cabin air filter cleans the HVAC air you breathe inside the truck.

For a 2018 Ford F-350-Super-Duty, the engine filter safeguards mass airflow readings and throttle response by keeping dust and debris out of the intake tract.
