Delphi AF10577 Mass Air Flow Sensor

Delphi AF10577 Mass Air Flow Sensor

The Delphi AF10577 is a premium mass air flow sensor probe built with OE heritage and knowledge drawn from more than 100 years of original-equipment experience. It is a bolt-on, black, blade-terminal sensor with a single rectangular female connector and no housing or wiring harness included.

Compatible With select vehicle applications that use this style of Delphi mass air flow sensor, including Suzuki Swift and related interchange references for the same application. The AF10577 part number is also commonly searched for OE-style replacement needs on import engine management systems.

Key Features

• Mass air flow sensor probe only with instruction sheet
• Premium item grade for engine air measurement service
• Bolt-on mounting type for direct replacement use
• 5-terminal blade connection with one rectangular female connector
• No housing included and no wiring harness included
• Black sensor body
• Delphi AF10577 part number for catalog and search matching

Product Details

The Delphi AF10577 measures incoming air so the engine control module can calculate fuel delivery and airflow strategy more accurately. Delphi builds this sensor using OE-based design knowledge developed through long-term supplier experience with major automakers, which helps support consistent signal output in emission control and fuel management systems. If you are sourcing a replacement mass air flow sensor for Suzuki Swift applications or cross-referencing by part number, AF10577 is a direct catalog match to review.

This part cross-references Hitachi Automotive MAF0107 and Standard Ignition MAS0404 for the same application.

Common Issues It Can Help Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to airflow sensor faults
• Poor fuel trim behavior from incorrect air measurement
• Driveability problems tied to contaminated or failing MAF signal output

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This probe-only design does not include a housing or wiring harness, so reuse of the existing intake assembly is required where applicable. Follow the included instruction sheet, inspect the intake tract for dirt or oil contamination, and clear diagnostic codes after installation if the vehicle requires it.

Quality Assurance

Delphi applies OE heritage and supplier experience to aftermarket emission control sensors, including the AF10577 mass air flow sensor. That OE-based background supports consistent part design and application-focused replacement quality.
