Spectra MA471 Mass Air Flow Sensor
The Spectra MA471 mass air flow sensor is built for direct replacement service on select Porsche applications with an integrated housing. It is engineered to deliver a faster signal response and steady airflow measurement for 2005-2008 Porsche Boxster and 2006-2008 Porsche Cayman models.
Key Features
- Programmable ceramic circuit board with premium-grade silicon coating
- Helps protect the sensor from under-hood heat swings and road vibration
- Uses platinum resistance thermometer sensor technology for consistent signal output
- Direct-fit replacement for select Porsche Boxster and Porsche Cayman applications
- Cross-references Bosch 0280218145 and Standard Ignition MAS0418
Detailed Description
The Spectra MA471 is a mass air flow sensor for vehicles equipped with an integrated housing, including Fits 2005-2008 Porsche Boxster, N/A and Fits 2006-2008 Porsche Cayman, N/A. It measures incoming air so the engine control system can calculate fuel delivery more accurately. The sensor’s circuit board design and protective silicon coating are intended to improve durability in demanding engine-bay conditions, while the platinum resistance thermometer elements support responsive airflow readings. This part number, MA471, is a practical OE-style replacement for Porsche Boxster and Porsche Cayman air metering service.
What It Helps Address
- Rough idle caused by inaccurate airflow readings
- Check engine light concerns related to mass air flow sensor performance
- Hesitation or poor throttle response during acceleration
- Fuel trim issues from incorrect air measurement
- Driveability problems tied to a failing MAF sensor
Installation Notes and Tips
Verify the vehicle uses the integrated housing configuration before ordering. Compare the connector, housing style, and OE part number against the original unit on the vehicle. For best results, inspect the intake tract for leaks or contamination before installing the new MA471 sensor. Confirm fitment for your specific Porsche Boxster or Porsche Cayman model year before installation.
Quality Assurance
Spectra designs this sensor with a programmable ceramic circuit board and protective silicon coating to support stable operation in high-heat, high-vibration environments. The MA471 is built around platinum resistance thermometer sensor technology for consistent signal response.
