Standard Ignition MAS0123 Mass Air Flow Sensor

Mass Air Flow Sensor for Ford and Mercury Applications

Standard Ignition MAS0123 is a new mass air flow sensor built for accurate airflow measurement and stable engine management. It is engineered to deliver reliable airflow readings to the ECU under demanding operating conditions, helping maintain the correct air/fuel balance for cleaner combustion.

Compatible with select Ford Mustang, Ford Taurus, Mercury Sable, and related applications, MAS0123 is a sensor-only replacement with an oval female connector and screw-on attachment style.

Key Features

• 100% new, never remanufactured construction
• Computer-tested for accurate airflow output to the ECU
• Proprietary sensing elements for consistent readings across a wide temperature range
• Sensor-only design with no housing included
• Metal and plastic construction for OE-style fitment
• Oval female connector with 4 male blade terminals
• Screw-on attachment with 2 bolt holes

Detailed Description

Standard Ignition MAS0123 is a direct-fit mass air flow sensor for vehicles that rely on precise intake air measurement to manage fuel delivery and drivability. This part number is commonly cross-referenced with Delphi AF10111 for the same application. The MAS0123 is built to provide accurate airflow signals across changing ambient temperatures, supporting consistent ECU response in Ford Mustang, Ford Taurus, Mercury Sable, and other listed vehicles.

Because the sensor is supplied without a housing, it is intended for service where the original housing remains in place and only the sensing unit needs replacement. The screw-on mounting style, oval connector shape, and 4-terminal blade interface help match the original equipment configuration on supported vehicles.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation during acceleration from incorrect air/fuel calculation
• Check engine light concerns related to mass air flow sensor performance
• Poor fuel economy linked to faulty intake air measurement
• Driveability issues under changing temperature conditions

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. MAS0123 uses a female oval connector, 4 male blade terminals, and a screw-on attachment with 2 bolt holes. Since this is a sensor-only part, confirm that the existing housing is serviceable and free of contamination before reassembly. For best results, inspect the intake tract for leaks or debris that could affect airflow readings.
