BSE Original 221058M Mass Air Flow Sensor Remanufactured

The BSE Original 221058M is a remanufactured mass air flow (MAF) sensor designed to restore accurate air intake measurement to your engine management system. The MAF sensor monitors the volume and density of air entering the engine, providing critical data to the engine control unit for proper fuel delivery and ignition timing. A faulty or degraded MAF sensor can cause poor fuel economy, rough idling, hesitation, or a check engine light — replacing it with a remanufactured unit restores factory-level performance at a cost-effective price point.

Key Features:

• Remanufactured mass air flow sensor
• Bolt-on mounting with 2 mounting holes for straightforward installation
• Single female connector with 5 male blade terminals
• Plastic housing construction
• No flash or ECU reprogramming required
• Sensor only — no housing included

This sensor fits a wide range of select 2003–2024 Nissan, INFINITI, and Suzuki vehicles. Note that some applications may require the engine control module to be cleared of any stored MAF-related diagnostic codes after installation.
