Mass Air Flow Sensor (99-05 V8 F-150)Find parts that fit my vehicle

Accurate Air Measurement for Optimized Performance. This Mass Air Flow Sensor delivers precise readings of intake air volume using a hot-film element, enabling the engine control unit to calculate the correct fuel injection pulse width. When the factory sensor fails or drifts, it can cause rough idle, poor throttle response, or check-engine lights. Installing a new, calibrated unit restores engine smoothness, correct air-fuel ratio, and reliable emissions compliance.

Durable, OEM-Grade Construction. Encased in high-temperature-resistant nylon, the sensor housing withstands underhood heat and chemical exposure. The hot-film element is protected behind a fine mesh screen that blocks debris while allowing laminar airflow. The integrated connector matches factory pin arrangements for a seamless electrical connection.

Installation. Disconnect the negative battery terminal, unplug the factory sensor harness, remove the retaining screws, swap in the new sensor with a clean O-ring, secure with screws, plug in the harness, and reconnect the battery.

Application. This Mass Air Flow Sensor fits 1999–2005 light vehicles equipped with the V8 F-150 engine and corresponding airflow meter housing.
