BSE Original 29051 Mass Air Flow Sensor Remanufactured, 3-Terminal Blade

The BSE Original 29051 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 intake, feeding critical data to the ECU to maintain proper fuel trim and combustion efficiency. A failing sensor commonly triggers check engine lights, rough idle, poor fuel economy, and hesitation — replacing it with a quality remanufactured unit brings performance back to factory specification.

Key Features:

• Remanufactured mass air flow sensor
• Screw-in mounting type for straightforward installation
• 3-terminal male blade connector
• Plastic housing construction
• Sensor only — no housing included
• No ECU flash or reprogramming required

This sensor fits select 1998–2004 Nissan, Mercury, and INFINITI vehicles. Confirm fitment against your vehicle's year, make, model, and engine before ordering.
