2013 Ford Flex Air Filter in Westborough, MA

It’s in the engine bay inside a sealed air box connected to the intake ducting.

The air box is typically mounted near the front of the bay and feeds the 3.5L V6 twin‑turbo intake path. Opening the box exposes a flat, panel‑style filter that can be inspected or replaced. Keeping this filter clean helps the 365‑hp engine breathe properly for consistent power and fuel economy around Westborough and MetroWest.

• Access via the under‑hood air box with latches or screws
• Panel‑style filter sits ahead of the mass airflow (MAF) sensor
• Schedule an inspection: schedule service

The engine air filter protects the 3.5L V6 twin‑turbo intake, while the cabin air filter cleans air entering the HVAC for passengers.

The engine filter stops dust before it reaches the intake tract and MAF sensor, supporting performance and efficiency. The cabin filter traps pollen and particulates so everyone inside breathes cleaner air. Both filters are serviceable and designed to be replaced when contaminated.

• Engine filter: airflow to combustion, power, and mpg
• Cabin filter: HVAC airflow quality and odor control
• OEM‑spec parts available at Herb Chambers Ford of Westborough

Typical signs include reduced acceleration, lower fuel economy, rough idle (engine filter), and weak HVAC airflow or musty odors (cabin filter).

As the 3.5L V6’s intake filter loads with debris, the engine may feel sluggish and less responsive in Westborough stop‑and‑go traffic. A dirty cabin filter makes the fan work harder, reducing defrost/AC performance and allowing odors to linger. Addressing both protects comfort and drivability.

• Engine: hesitation, darker filter media, more intake noise
• Cabin: noisy blower with less airflow, persistent smell
• Book diagnostics: schedule service
