The engine air filter sits inside the air cleaner box in the front-left of the engine bay on the 3.5L V6.

Lift the hood and locate the rectangular housing with clips and an intake snorkel; that’s the Flex’s airbox. The cabin air filter, by contrast, is typically accessed behind the glove box. If you’re unsure, we can show you the access points during your appointment in Westborough.

The engine air filter cleans air for combustion, while the cabin air filter cleans air entering the HVAC for passengers.

On the 3.5L V6 Flex, the engine filter protects the intake, helps maintain power, and supports fuel economy. The cabin filter targets dust, pollen, and debris before it reaches vents and the evaporator. Each part has a different location, service interval, and performance impact.

• Engine filter: intake protection and performance
• Cabin filter: HVAC airflow and in-cabin air quality
• Replace on their respective OEM intervals

Engine: reduced power, lower MPG, or rough idle; Cabin: weak airflow, musty odors, or noisy fan.

Because the Flex’s 3.5L V6 relies on steady airflow, a dirty engine filter can dull throttle response and fuel economy. A saturated cabin filter can strain the blower motor and leave dusty vents. If you notice these symptoms, book a quick inspection in Westborough.
