Global Parts 1813203 Mass Air Flow Sensor

Mass Air Flow Sensor for Porsche Applications

Global Parts 1813203 is a mass air flow sensor for select Porsche intake systems. 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. This part number 1813203 is a direct-fit option for specific Porsche Boxster and Porsche 911 models with w/o Electronic accel configurations.

Key Features

• Measures intake air volume and density for engine management input
• Supports precise fuel injection and ignition timing control
• Fits 1997-2004 Porsche Boxster, N/A, w/o Electronic accel
• Fits 1999-2001 Porsche 911, N/A, w/o Electronic accel
• Global Parts part number 1813203 for targeted OE-style replacement

Detailed Description

The Global Parts 1813203 mass air flow sensor is built for Porsche vehicles that rely on accurate airflow data to manage combustion. By reporting the amount of air entering the engine, the sensor helps the ECU maintain proper fueling and timing under changing load and throttle conditions. This part cross-references Delphi AF10584 for the same application. It is a fitment-based replacement for Porsche Boxster and Porsche 911 models listed below, and the part number 1813203 should be matched to the vehicle configuration before ordering.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Lean or rich fuel mixture concerns
• Reduced fuel economy from incorrect air metering
• Check engine light conditions related to airflow sensor performance

Installation Notes and Tips

Verify the vehicle year, model, and throttle configuration before installation. This sensor fits 1997-2004 Porsche Boxster, N/A, w/o Electronic accel and 1999-2001 Porsche 911, N/A, w/o Electronic accel. Inspect the intake tract, air filter housing, and electrical connector for contamination or damage before replacing the sensor. Confirm the connector and mounting style match the original unit.

Quality Assurance

Global Parts supplies this mass air flow sensor as a replacement component for the listed Porsche applications. The design follows the airflow-measurement function required by the engine control system for accurate fuel and ignition control.
