Key Features

• NTK Mass Air Flow Sensor line for emission control applications
• OE-focused design backed by NTK technical sensor experience
• Built to meet or exceed OE specifications
• Tested under thermal shock, vibration, and OBD verification conditions
• Direct replacement for select import and domestic vehicles
• Part number MG0004 for catalog and service lookup

Product Details

NTK expands its sensor coverage with the MG0004, part of the NTK Mass Air Flow Sensor line. Drawing on OE supplier experience, NTK manufactures technical sensors for import and domestic vehicles with attention to signal accuracy, durability, and application-specific fitment. This sensor is used on 1999-2005 Buick LeSabre and Park Avenue, 2000-2005 Chevrolet Impala, 1999-2005 Chevrolet Monte Carlo, 1999-2005 Pontiac Bonneville, 1999-2004 Buick Regal, 1999-2003 Pontiac Grand Prix, and additional listed applications such as Camaro, Firebird, Riviera, Lumina, 88, Intrigue, and LSS. If you are servicing a Buick LeSabre mass air flow sensor or replacing a Chevrolet Impala MAF sensor, MG0004 is the catalog reference to verify.

This part cross-references Delphi AF10126 and Standard Ignition MAS0193 for the same application.

What It Helps Address

• Rough idle caused by incorrect airflow measurement
• Hesitation or poor throttle response from inaccurate air metering
• Fuel trim issues related to a failing MAF sensor
• Check engine light concerns tied to airflow sensor faults
• Driveability problems on Buick, Chevrolet, Pontiac, and Oldsmobile vehicles

Installation Notes

Verify the vehicle year, make, model, and engine application before ordering. Compare the connector, housing style, and sensor location on the original unit to confirm MG0004 match-up. After installation, clear diagnostic trouble codes and confirm airflow readings with a scan tool if available. For best results, inspect the air intake tract for leaks, contamination, or damaged ducting that can affect sensor performance.

Quality Assurance

NTK states that its technical sensors are tested for thermal shock, vibration, and OBD verification, and are manufactured to meet or exceed OE specifications. The MG0004 is supported by NTK’s OE-focused sensor development for the aftermarket.
