Standard Ignition MAS0134 Mass Air Flow Sensor

Mass Air Flow Sensor for Ford and Lincoln

The Standard Ignition MAS0134 is a complete mass air flow sensor assembly for select Ford and Lincoln applications. It provides accurate airflow input to the ECU so the engine can maintain the proper air/fuel ratio during changing load conditions.

• 100% new, never remanufactured construction
• Computer-tested for accurate airflow readings under hard engine conditions
• Hybrid electronic circuitry for reliable signal output
• No moving parts for wear-free sensor life
• Bolt-on installation with metal housing included
• Rectangular female connector with 4 blade terminals

Detailed Product Overview

Standard Ignition MAS0134 is built as a complete assembly with a metal housing and a 4-bolt, bolt-on attachment method. The sensor uses a rectangular female connector and 4 male blade terminals for the factory-style electrical interface. As a mass air flow sensor, it measures incoming air so the engine control module can adjust fuel delivery for cleaner combustion and stable drivability. This part number is commonly searched for Ford F-150 mass air flow sensor replacement, Ford Mustang MAF sensor replacement, and Lincoln Navigator airflow sensor service.

Compatible With select 1995-2004 Ford and Lincoln vehicles, including 1997-2004 Ford Expedition, 1997-1998 Ford F-150, 1996-1998 Ford Mustang, and 1998 Lincoln Navigator. The MAS0134 part number is also referenced in Ford F-250, Ford F-350, Ford Taurus, Lincoln Continental, and E-Series applications listed in the fitment data.

This part cross-references Delphi AF10119 and Spectra Premium MA166 for the same application.

Common Problems This Sensor Can Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Rich or lean fuel trim conditions from faulty MAF input
• Check engine light related to airflow sensor performance
• Poor throttle response under load

Installation Notes and Tips

Verify connector shape, terminal count, and bolt pattern before installation. Inspect the intake tract for dirt, oil contamination, or air leaks that can affect sensor readings. Clear diagnostic trouble codes after replacement and confirm the ECU relearns airflow values during a road test. Use the MAS0134 part number to confirm the correct Ford F-150, Ford Mustang, or Lincoln Navigator application before ordering.

Quality Assurance

Standard Ignition supplies this sensor as a new unit rather than a remanufactured part, helping avoid leftover debris from prior use. Each unit is computer-tested to verify airflow signal accuracy, and the hybrid electronic design supports consistent circuit performance.
