Spectra MA475 Mass Air Flow Sensor
The Spectra MA475 mass air flow sensor is a standard replacement part for precise airflow measurement in select Porsche applications. It is built with a programmable ceramic circuit board and premium silicon coating to help protect the sensor from under-hood heat swings and vibration, while the platinum resistance thermometer design supports quicker signal response and consistent readings.
Key Features
- Standard replacement mass air flow sensor for emission control systems
- Programmable ceramic circuit board with premium silicon coating
- Platinum resistance thermometer sensor design for responsive signal output
- Black plastic housing with oval male connector
- 5-terminal blade connection
- No housing, wiring harness, mounting bracket, or mounting hardware included
Detailed Description
The Spectra MA475 is engineered for direct airflow sensing in Porsche Boxster and Porsche 911 models that rely on accurate mass air data for engine management. By measuring incoming air volume and sending a stable signal to the control system, this sensor supports proper fuel delivery and drivability. The MA475 part number is a practical OE-style replacement choice for drivers servicing a Porsche Boxster mass air flow sensor or a Porsche 911 mass air flow sensor.
This part cross-references Delphi AF10584 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 faults
- Poor fuel metering from inconsistent sensor output
- Driveability issues tied to heat- or vibration-related sensor wear
Installation Notes and Tips
Verify connector shape, terminal count, and mounting style before installation. The MA475 uses a 1-connector oval male blade terminal design and does not include a housing or harness, so the existing vehicle connector and intake setup must match. Confirm fitment for 1997-2005 Porsche Boxster and 1999-2003 Porsche 911 before ordering.
