Product Details

NTK MG0039 is engineered for vehicles that rely on precise airflow input for engine management. As part of the NTK Mass Air Flow Sensor product line, it reflects NTK’s OE supplier background and focus on technical sensor coverage for import and domestic vehicles. This part cross-references Delphi AF10216 for the same application.

Compatible With 2003-2004 INFINITI I35, mass air flow sensor only; 2003 INFINITI G35, mass air flow sensor only; and 2003 Nissan Maxima, mass air flow sensor only. The MG0039 part number is also referenced in aftermarket catalogs for these applications.

Common Replacement Reasons

• Check engine light related to airflow sensor performance
• Rough idle or unstable engine speed
• Hesitation during acceleration
• Incorrect air-fuel mixture readings
• Reduced drivability caused by a failing mass air flow sensor

Installation Notes

Verify the connector style, sensor location, and vehicle application before installation. Compare the original sensor to the NTK MG0039 and confirm the part number against the vehicle’s service information for 2003-2004 INFINITI I35, 2003 INFINITI G35, or 2003 Nissan Maxima. Follow factory diagnostic and relearn procedures if required by the vehicle.

Quality Assurance

NTK sensors are manufactured to meet or exceed OE specifications and are backed by testing that includes thermal shock, vibration, and OBD verification. The MG0039 reflects NTK’s OE-level sensor development for import vehicle coverage.
