2017 Ford Flex in Mesa, AZ | Larry H. Miller Ford Mesa

The engine air filter sits in the engine bay inside the intake airbox ahead of the engine.

On the 2017 Ford Flex with the 3.5L V6 (engine code 6VNAG3.5), the panel-style filter is housed in a rectangular airbox connected to the intake duct. Release the clips or screws, lift the cover, and swap the filter with the airflow arrow oriented correctly. In Mesa’s dusty conditions, inspecting this housing helps prevent debris from reaching the mass airflow sensor. If you prefer a pro install, schedule service.

We install genuine Ford OEM (Motorcraft) filters for proper fit and filtration. See current service specials or schedule an appointment.
