Mass Air Flow Sensor for Audi A8

Global Parts 1813220 is a mass air flow sensor for the intake system on select Audi A8 and Audi A8 Quattro models. It measures incoming air volume and density so the engine control unit can calculate fuel delivery and ignition timing with the correct air-fuel balance.

Fits 1997-1999 Audi A8, sensor only. Fits 1997-1999 Audi A8 Quattro, sensor only.

Key Features

• Measures intake air volume and density for engine management
• Supports precise fuel injection and ignition timing control
• Direct application for 1997-1999 Audi A8 and Audi A8 Quattro
• Global Parts part number 1813220 for catalog matching
• Cross-reference: Delphi AF10558 for the same application

Detailed Description

This Global Parts mass air flow sensor is built for vehicles that rely on accurate airflow data to maintain proper combustion. On Audi A8 and Audi A8 Quattro applications, the sensor reports intake air conditions to the ECU so the engine can adjust fueling and timing based on real operating conditions. Part number 1813220 is also referenced against OE-style numbers 077133471D and 771334714.

Use this sensor when servicing a drivability concern tied to incorrect airflow measurement on 1997-1999 Audi A8 or 1997-1999 Audi A8 Quattro models.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Fuel mixture faults related to intake air measurement
• Poor engine response from incorrect ECU air data
• Check engine light conditions tied to the MAF circuit

Installation Notes and Tips

Verify the connector style and sensor-only configuration before installation. Inspect the intake tract for leaks, contamination, or damaged wiring, since those issues can affect airflow readings even with a new sensor. Confirm the vehicle application by year and model before ordering Global Parts 1813220.
