NTK MG0189 Mass Air Flow Sensor

NTK Mass Air Flow Sensor for BMW Applications

The NTK Mass Air Flow Sensor, part number MG0189, is a technical sensor built for BMW applications that require accurate airflow measurement and OE-level signal quality. It is part of NTK’s sensor-focused product line and reflects the brand’s OE experience in the aftermarket.

• Mass air flow sensor for emission control and engine management systems.
• OE-specification manufacturing focus for consistent sensor output.
• Tested under thermal shock, vibration, and OBD verification conditions.
• NTK Mass Air Flow Sensor line from a brand with broad technical sensor coverage.

Detailed Fitment and Application

Fits 2004-2006 BMW X5, N/A. Fits 2004-2005 BMW 545i, N/A. Fits 2004-2005 BMW 645Ci, N/A. Fits 2004-2005 BMW 745i, N/A. Fits 2004-2005 BMW 745Li, N/A. This part cross-references Bosch 0280218135 and Delphi AF10526 for the same application. The MG0189 is intended for vehicles using a sensor module with housing, and it supports the airflow data the engine control system uses to manage fuel delivery and drivability. For BMW X5 and other listed BMW models, the sensor is positioned as a direct replacement option within the specified application coverage.

What It Helps Address

• Incorrect airflow readings that can affect fuel metering.
• Rough idle caused by inconsistent sensor output.
• Driveability issues related to inaccurate intake air measurement.
• OBD faults tied to mass air flow sensor performance.
• Replacement needs for a worn or failing airflow sensor module.

Installation Notes and Quality Assurance

Verify the sensor module with housing configuration before ordering, since the fitment notes specify that setup. Confirm the connector and application details against the vehicle’s original sensor arrangement. NTK states that its sensors are manufactured to meet or exceed OE specifications and are validated through thermal shock, vibration, and OBD testing. Part number MG0189 is supported by NTK’s OE-focused technical sensor program.
