Spectra MA447 Mass Air Flow Sensor

Spectra MA447 Mass Air Flow Sensor

The Spectra MA447 mass air flow sensor is built for precise airflow measurement and stable engine management response. It is a direct-fit emission control sensor for select Nissan and INFINITI applications, including Murano, Pathfinder, Altima, Quest, Rogue, Maxima, and QX60 models.

Key Features

• Programmable ceramic circuit board with premium-grade silicon coating
• Helps protect the sensor from under-hood heat swings and road vibration
• Fast signal response for consistent airflow feedback
• Uses platinum resistance thermometer sensor technology
• Direct replacement for select OE-style mass air flow sensor applications

Detailed Description

The Spectra MA447 is a mass air flow sensor engineered to measure incoming air so the engine control system can manage fuel delivery accurately. Its ceramic circuit board and protective silicon coating are built to handle demanding under-hood conditions, while the platinum resistance thermometer sensor design supports responsive signal output. This part cross-references Hitachi Automotive MAF0123 and Standard Ignition MAS0467 for the same application. Fits 2015-2020 Nissan Murano, N/A; Fits 2015-2020 Nissan Pathfinder, N/A; Fits 2015-2018 Nissan Altima, N/A; Fits 2015-2017 Nissan Quest, N/A; Fits 2016-2017 Nissan Rogue, N/A; Fits 2016 INFINITI QX60, N/A; Fits 2016 Nissan Maxima, N/A; Fits 2015 INFINITI QX60, N/A; Fits 2015 Nissan Maxima, N/A; Fits 2014-2015 Nissan Rogue, N/A.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Check engine light related to mass air flow sensor performance
• Hesitation or poor throttle response during acceleration
• Fuel trim issues tied to incorrect air measurement
• Driveability problems on Nissan and INFINITI vehicles with MAF sensor faults

Installation Notes and Tips

Verify the connector style and application notes before installation, especially on 2016-2017 Rogue and 2016 Maxima models marked sensor only to 01/2016. Confirm the vehicle’s original sensor configuration against the fitment notes for Murano, Pathfinder, Altima, Quest, Rogue, Maxima, and QX60. After installation, clear diagnostic trouble codes and perform a relearn or idle verification if required by the vehicle service procedure.

Quality Assurance

Spectra manufactures this sensor with a programmable ceramic circuit board and protective silicon coating to support durability in heat and vibration exposure. The MA447 is built as an OE-style replacement for select Nissan and INFINITI emission control applications.
