Spectra MA494 Mass Air Flow Sensor
The Spectra MA494 mass air flow sensor is a standard replacement emission control sensor built for accurate airflow measurement and stable engine management. It features a black plastic housing, a single oval male connector, and a 4-terminal blade design for direct-fit service on select Mercedes-Benz diesel applications.
Fits 2016-2017 Mercedes-Benz GLE300d, N/A. Fits 2014-2017 Mercedes-Benz Sprinter 2500, N/A. Fits 2014-2017 Mercedes-Benz Sprinter 3500, N/A. Fits 2014-2016 Mercedes-Benz E250, N/A. Fits 2013-2015 Mercedes-Benz GLK250, N/A. Fits 2015 Mercedes-Benz ML250, N/A.
Key Features
- Standard replacement mass air flow sensor for emission control service
- Black plastic housing included for direct installation
- Single oval connector with male terminal design
- 4-terminal blade configuration
- 81 mm inlet and outlet connection diameters
- Programmable ceramic circuit board with premium silicon coating for thermal and vibration resistance
- Platinum resistance thermometer sensor technology for faster signal response and consistent readings
Detailed Description
Spectra MA494 is engineered for Mercedes-Benz diesel models that rely on precise airflow data for fuel delivery and drivability. The sensor uses a programmable ceramic circuit board with premium silicon coating to help protect the electronics from under-hood heat swings and road vibration, while the platinum resistance thermometer sensor design supports quicker signal response and steady measurement output. This part cross-references Delphi AF10676 for the same application. If you are replacing a worn Mercedes-Benz Sprinter 2500 mass air flow sensor, Mercedes-Benz E250 MAF sensor, or Mercedes-Benz GLE300d airflow sensor, MA494 provides the correct OE-style service fitment.
What It Helps Solve
- 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 mixture issues from incorrect intake air measurement
- Driveability problems tied to a failing Mercedes-Benz diesel MAF sensor
Installation Notes and Tips
Verify connector shape, terminal count, and inlet/outlet diameter before installation. Inspect the intake tract, air filter housing, and wiring connector for contamination or damage before replacing the sensor. After installation, clear diagnostic trouble codes and confirm proper idle and throttle response with a scan tool if needed.
Quality Assurance
Spectra MA494 is built as a standard replacement sensor for select Mercedes-Benz applications, with construction details focused on heat resistance, vibration tolerance, and signal consistency. It is intended for direct-fit service on listed vehicles including Mercedes-Benz Sprinter 3500, Mercedes-Benz ML250, and Mercedes-Benz GLK250 applications.
