It is a direct replacement style sensor for vehicles such as the 1999-2005 Buick LeSabre, 2004-2005 Chevrolet Impala, and 1999-2003 Pontiac Grand Prix. This part cross-references Delphi AF10126 for the same application.

Common Issues It May Address

• Rough idle caused by incorrect airflow readings
• Hesitation or poor throttle response during acceleration
• Reduced fuel economy from inaccurate air metering
• Check engine light related to mass air flow sensor faults
• Driveability problems on GM intake systems using sensor-only service parts
