BSE Original 221041M Mass Air Flow Sensor Remanufactured

The BSE Original 221041M is a remanufactured mass air flow (MAF) sensor designed to measure the volume and density of air entering the engine, providing the engine control module with the data it needs to deliver the correct fuel mixture. A faulty MAF sensor can trigger check engine lights, cause rough idle, poor fuel economy, and hesitation under acceleration — making a quality replacement essential for restoring proper engine management.

• Remanufactured sensor assembly — housing included
• Plastic housing with bolt-on mounting for straightforward installation
• Single rectangular female connector with 3 blade-style male terminals
• No ECU flash or reprogramming required after installation
