BSE Original 20864M Mass Air Flow Sensor Remanufactured, 6-Terminal

The BSE Original 20864M is a remanufactured mass air flow (MAF) sensor designed to restore accurate airflow measurement to your engine management system. The MAF sensor monitors the volume and density of air entering the engine, providing critical data to the ECU for precise fuel delivery and ignition timing. A faulty or failing sensor can result in rough idle, poor fuel economy, hesitation, and failed emissions tests — making a quality replacement essential.

• Remanufactured mass air flow sensor
• Sensor only — no housing included
• 6-terminal, blade-style male terminals with female connector
• Plastic housing construction
• Screw-in mounting type
• No ECU flash or reprogramming required after installation

This BSE Original remanufactured MAF sensor is built to meet OE performance standards and fits select 2000–2005 Ford, Lincoln, and Mercury models. Sensor only — verify your vehicle's housing compatibility before ordering.
