This part cross-references Delphi AF10168 and Standard Ignition MAS0144 for the same application.

What It Helps Address

  • Rough idle caused by inaccurate airflow readings
  • Hesitation or poor throttle response
  • Fuel trim issues related to incorrect air measurement
  • Check engine light concerns tied to mass air flow sensor faults
  • Driveability problems on select Nissan and INFINITI models

Installation Notes

Verify the vehicle application by year, make, and model before installation. This sensor is listed for N/A position applications only, so match the original sensor location and connector style to the OE part. After installation, clear diagnostic trouble codes and confirm proper idle quality and airflow signal response.
