Detailed Product Overview

The Delphi AF10513 is engineered for vehicles that use a probe-only MAF sensor configuration. It measures incoming air so the engine control system can calculate fuel delivery and maintain proper drivability. This part is a direct-fit style service component for the Audi RS4 and is listed for 2007-2008 Audi RS4 applications with probe-only mass air flow sensors.

This part cross-references Spectra Premium MA126 for the same application. The AF10513 part number is also associated with OE-style interchange references used in the same vehicle coverage.

Common Problems This Sensor May Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to mass air flow sensor performance
• Poor fuel metering from a failing airflow signal
• Driveability issues on 2007-2008 Audi RS4 models with probe-only sensor setups

Installation Notes and Tips

Verify the connector style, terminal count, and probe-only configuration before installation. This Delphi AF10513 uses a bolt-on mount, a female oval connector, and a 5-terminal blade layout. Confirm the vehicle is a 2007-2008 Audi RS4 with a probe-only mass air flow sensor before ordering or replacing the part.

Quality Assurance

Delphi builds aftermarket parts using OE experience and supplier knowledge developed over decades of original equipment service. That background is reflected in the AF10513 standard replacement sensor for Audi RS4 airflow management service.
