Mass Air Flow Sensor Direct-Fit Replacement for Ford C-Max, Escape, Focus, Fusion, Transit

This Mass Air Flow Sensor is a direct-fit replacement designed to keep your Ford C-MAX, Escape, Focus, Fusion, or Transit running smoothly. By precisely measuring the amount of air entering the engine, it helps the Powertrain Control Module (PCM) calculate the right fuel-to-air ratio. That means steadier idle, crisp throttle response, and improved fuel efficiency, even in stop-and-go city driving or highway acceleration. If your vehicle is showing symptoms like rough idle, misfires, or reduced MPG, a fresh MAF sensor can restore your engine’s breathing and restore performance without unnecessary repairs.

Designed for broad compatibility, this sensor supports a wide range of Ford and Lincoln vehicles, including C-MAX, Escape, F-650, F-750, Focus, Fusion, Transit Connect, Lincoln MKZ, Jaguar XF, and several Volvo configurations. It aligns with OEM references and multiple part numbers to ensure you’re getting a precise match for your vehicle’s intake system. The result is a reliable, factory-style replacement that’s built to withstand daily operation and the heat of the engine bay.
