BSE Original 221042M Mass Air Flow Sensor Remanufactured

The BSE Original 221042M is a remanufactured mass air flow (MAF) sensor designed as a direct-fit replacement for a wide range of Ford, Lincoln, Mazda, and Mercury vehicles. The mass air flow sensor measures the volume and density of air entering the engine, providing critical data to the engine control module for precise fuel delivery and ignition timing. A faulty MAF sensor commonly causes rough idle, poor fuel economy, hesitation, or a check engine light — making a quality replacement essential for restoring proper engine performance.

Key Features:

• Remanufactured mass air flow sensor
• Bolt-on mounting for straightforward installation
• Single rectangular female connector with 6 male blade terminals
• Plastic housing construction
• Sensor only — no housing included
• No flash or programming required

Fits select 2003–2016 Ford, Lincoln, Mazda, and Mercury models. Supplied as sensor only; the original housing is retained during installation.
