Standard Ignition MAS0167 Mass Air Flow Sensor

Mass Air Flow Sensor for Lincoln Navigator

Restore accurate airflow measurement with this Standard Ignition mass air flow sensor, part number MAS0167. It is a complete bolt-on assembly built for 2003-2004 Lincoln Navigator applications and engineered to deliver reliable airflow data to the ECU for proper air/fuel ratio control.

Key Features

• 100% new, never remanufactured construction
• Computer-tested for accurate airflow readings under demanding engine conditions
• Complete assembly with housing included
• Bolt-on attachment method for straightforward replacement
• Plastic housing with a rectangular female connector
• 4-bolt mounting design with 4 blade terminals

Detailed Description

The Standard Ignition MAS0167 mass air flow sensor is built to replace a failing or inaccurate airflow sensor in 2003-2004 Lincoln Navigator models. By measuring incoming air and sending precise data to the engine control unit, this sensor helps the engine maintain the correct air/fuel balance for clean combustion and stable performance. The MAS0167 is manufactured as a new unit rather than remanufactured, reducing the risk of contamination from leftover debris that can affect sensor operation.

This Lincoln Navigator mass air flow sensor is also subjected to durability and environmental testing to support consistent operation in harsh driving conditions. If you are searching for a 2003 Lincoln Navigator mass air flow sensor or a 2004 Lincoln Navigator MAF sensor replacement, MAS0167 provides a direct-fit solution with the correct connector style, bolt pattern, and complete housing assembly.

This part cross-references Delphi AF10131 and Hitachi Automotive MA0044 for the same application.

What It Helps Fix

• Rough idle caused by incorrect airflow readings
• Hesitation or stumble during acceleration
• Lean or rich air/fuel mixture concerns
• Check engine light related to mass air flow sensor performance
• Reduced drivability from inaccurate ECU airflow input

Installation Notes and Tips

Verify connector shape, terminal count, and bolt pattern before installation. This MAS0167 sensor uses a bolt-on mounting style, a rectangular female connector, and a complete assembly layout with housing included. Inspect the intake tract for dirt, oil residue, or air leaks before installing the new sensor, since contamination upstream can affect airflow readings.

Quality Assurance

Standard Ignition manufactures this sensor to strict quality standards and tests each unit electronically to confirm accurate signal output. The part also undergoes durability and environmental validation to support dependable performance in everyday and severe driving conditions.
