Detailed Description

The Delphi AF10450 mass air flow sensor is built for vehicles that use a probe-only MAF setup, including select Infiniti Q50, Q70, and QX60 models as well as Nissan Altima, Murano, Pathfinder, and Sentra applications. Delphi’s OE background is reflected in the sensor’s premium construction and application-specific electrical design, helping maintain accurate airflow measurement for engine control systems. This part number, AF10450, is a practical replacement choice when the original sensor probe is worn, contaminated, or no longer reading correctly.

This part cross-references Hitachi Automotive MAF0102 and Standard Ignition MAS0339 for the same application.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to mass air flow sensor performance
• Poor fuel control from a failing probe-only MAF sensor
• Driveability issues on Infiniti Q50, Nissan Altima, and related applications

Installation Notes

Verify the vehicle uses a probe-only mass air flow sensor before ordering. Match the connector shape, terminal count, and mounting style to the original unit, and follow the included instruction sheet during installation. Clean surrounding intake components before replacement to reduce contamination of the new sensor. Confirm fitment carefully on 2016 Nissan Altima and 2016 Nissan Sentra applications, since the notes specify production cutoffs.

Quality Assurance

Delphi builds this sensor using OE heritage and knowledge developed through long-term supplier experience with major automakers. The AF10450 is a premium-grade replacement intended to meet the application-specific requirements of select Infiniti and Nissan vehicles.
