Spectra MA134 Mass Air Flow Sensor

The Spectra MA134 mass air flow sensor is a direct-fit emission control sensor for select Ford and Mercury applications with integrated housing. It uses a programmable ceramic circuit board with a protective silicon coating to help resist under-hood heat swings and road vibration, while platinum resistance thermometer sensing supports quicker signal response and stable airflow measurement.

Key Features

  • Mass air flow sensor with integrated housing for select Ford and Mercury vehicles
  • Programmable ceramic circuit board with premium silicon coating
  • Built to resist severe temperature fluctuations and road vibration
  • Platinum resistance thermometer sensor design for responsive signal output
  • Direct replacement for applications requiring Spectra MA134

Fitment

  • Fits 2001-2002 Mercury Cougar, N/A; mass air flow sensor with integrated housing.
  • Fits 1999 Ford Contour, N/A; sensor module with housing, to 05/25/1999.
  • Fits 1999 Mercury Cougar, N/A; sensor module with housing, to 05/25/1999.
  • Fits 1999 Mercury Mystique, N/A; sensor module with housing, to 05/03/1999.
  • Fits 1995-1998 Ford Contour, N/A; mass air flow sensor with integrated housing.
  • Fits 1995-1998 Mercury Mystique, N/A; mass air flow sensor with integrated housing.

What It Helps Address

  • Rough idle caused by inaccurate airflow measurement
  • Hesitation or stumble during acceleration
  • Check engine light related to airflow sensor performance
  • Fuel trim issues from incorrect air metering
  • Driveability problems on Ford Contour, Mercury Mystique, and Mercury Cougar applications

Installation Notes

Verify the housing style and production date before ordering, especially for 1999 Ford Contour, 1999 Mercury Cougar, and 1999 Mercury Mystique applications with cutoff dates. Confirm connector style and sensor module configuration against the original part before installation. This part cross-references Delphi AF10122 and Standard Ignition MAS0358 for the same application.

Quality Assurance

Spectra builds this sensor with a ceramic circuit board and protective coating to support durability in demanding under-hood conditions. The MA134 is engineered for consistent signal response in the listed Ford and Mercury fitments.
