Mass Air Flow Sensor for Ford, Lincoln, and Mercury

Standard Ignition MAS0248 is a complete mass air flow sensor assembly built for accurate airflow measurement and stable engine management. It is a new, computer-tested replacement designed to help the ECU maintain the correct air/fuel ratio for cleaner combustion, improved fuel economy, and reduced emissions.

Compatible with 2003-2004 Ford Crown Victoria, 2003-2004 Lincoln Town Car, and 2003-2004 Mercury Grand Marquis, this MAS0248 sensor is a direct-fit option for common airflow-related drivability concerns.

Key Features

  • 100% new, never remanufactured construction
  • Computer-tested for accurate airflow signal output
  • Complete assembly with housing included
  • Bolt-on attachment for direct replacement service
  • Plastic housing with rectangular connector design
  • 6-terminal blade-style electrical interface
  • Built to strict calibration and quality standards

Detailed Description

The Standard Ignition MAS0248 mass air flow sensor measures incoming air so the engine control unit can calculate fuel delivery under changing load conditions. Its new, non-remanufactured design helps avoid contamination from leftover debris, while factory-style calibration supports consistent readings during hard engine operation. For Ford Crown Victoria, Lincoln Town Car, and Mercury Grand Marquis applications, this sensor supports smoother engine response and cleaner running performance.

This part cross-references Delphi AF10130 and Spectra Premium MA147 for the same application.

What It Helps Solve

  • Rough idle caused by inaccurate airflow readings
  • Hesitation or stumble during acceleration
  • Check engine light concerns related to the MAF circuit
  • Poor fuel economy from incorrect air/fuel mixture control
  • Elevated emissions from improper combustion balance

Installation Notes and Tips

Install as a bolt-on complete assembly using the existing rectangular female connector and 4-bolt mounting pattern. Verify the intake tract is clean before installation, and inspect the air filter and ducting for contamination or leaks that can affect sensor readings. Confirm vehicle application carefully for 2003-2004 Ford Crown Victoria, 2003-2004 Lincoln Town Car, and 2003-2004 Mercury Grand Marquis; 2003-2004 Ford Crown Victoria excludes Police Package models.

Quality Assurance

Standard Ignition manufactures and calibrates this MAS0248 sensor to strict quality standards and tests each unit electronically to confirm accurate airflow signal output under demanding engine conditions.
