Spectra MA141 Mass Air Flow Sensor

The Spectra MA141 mass air flow sensor is built for direct replacement on select Subaru applications with integrated housing. It is engineered to deliver a faster signal response and stable airflow measurement for consistent engine management in Subaru Legacy, Forester, and Impreza 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
  • Supports quick signal response for accurate airflow readings
  • Direct-fit mass air flow sensor with integrated housing

Product Details

Built for 1990-1999 Subaru Legacy, 1998 Subaru Forester, and 1993-1998 Subaru Impreza, the Spectra MA141 is a replacement mass air flow sensor for vehicles that rely on precise intake air measurement for fuel and ignition control. The MA141 part number is a practical choice when servicing drivability concerns tied to airflow signal accuracy. This part cross-references Standard Ignition MAS0146 for the same application.

Common Issues It Can Help Address

  • Rough idle caused by inaccurate airflow readings
  • Hesitation or stumble during acceleration
  • Hard starting related to incorrect air metering
  • Check engine light conditions tied to MAF sensor performance
  • Poor fuel control from unstable sensor output

Installation Notes

Compatible With 1990-1999 Subaru Legacy, integrated housing; 1998 Subaru Forester, integrated housing; and 1993-1998 Subaru Impreza, integrated housing. Verify the connector style and housing configuration before installation. Clean the intake tract and inspect the air filter and ducting so the new MA141 sensor can read airflow accurately after replacement.

Quality Assurance

Spectra uses a ceramic circuit board with protective silicon coating and platinum resistance thermometer sensor design to support durability and signal consistency in demanding under-hood conditions.
