Standard Ignition MAS0111 Mass Air Flow Sensor

Mass Air Flow Sensor for Ford and Mercury

Standard Ignition MAS0111 is a new mass air flow sensor built for accurate airflow measurement and stable engine management. It is a sensor-only replacement with a screw-on attachment, oval female connector, and 4-blade male terminals for direct service on supported Ford and Mercury applications.

Key Features

• 100% new, never remanufactured construction
• Computer-tested for accurate airflow readings under demanding engine conditions
• Proprietary sensing elements for consistent output across a wide ambient temperature range
• Metal and plastic housing materials for OE-style service replacement
• Screw-on attachment method with 2 bolt holes
• Sensor only; housing not included

Detailed Description

The Standard Ignition MAS0111 mass air flow sensor measures incoming air so the ECU can calculate the correct air/fuel ratio. Accurate airflow data helps the engine maintain clean combustion and stable drivability, especially when load and temperature change. This part cross-references Delphi AF10116 and Walker Products 245-1018 for the same application. It is a direct-fit service part for 1993-1995 Ford Ranger, 1994-1995 Ford Escort, 1994-1995 Ford Taurus, 1994-1995 Mercury Sable, and 1994-1995 Mercury Tracer.

What It Helps Solve

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Lean or rich fuel mixture concerns
• Check engine light conditions related to mass air flow sensor performance
• Poor throttle response from a failing sensor element

Installation Notes and Tips

Verify the connector shape, terminal count, and screw-on mounting style before installation. MAS0111 is a sensor-only part, so reuse the existing housing where applicable. Inspect the intake tract, wiring connector, and mounting surface for contamination or damage before installing the new sensor. Confirm fitment by year, make, and model for Ford Ranger, Ford Escort, Ford Taurus, Mercury Sable, and Mercury Tracer applications.

Quality Assurance

Standard Ignition manufactures this sensor to strict quality standards and computer-tests each unit to confirm accurate ECU airflow input. The design uses proprietary sensing elements to maintain output consistency across changing temperatures and demanding operating conditions.
