Detailed Description

Global Parts 1813388 is built for BMW intake systems that rely on precise airflow input to manage combustion. By reporting the amount and density of air entering the engine, the sensor supports stable fuel control, smoother engine response, and efficient operation. This part number 1813388 is listed for 2003-2006 BMW 325Ci, 2003-2005 BMW 325i, 2004-2005 BMW X3, and 2003-2005 BMW Z4, all with sensor w/ housing notes.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response from incorrect air-fuel calculation
• Check engine light conditions related to mass air flow sensor faults
• Reduced fuel efficiency from improper fuel metering
• Driveability issues tied to contaminated or failing airflow sensing

Installation Notes and Tips

Verify the connector style, housing configuration, and OE number before installation. Confirm the vehicle application against the listed fitment for 2003-2006 BMW 325Ci, 2003-2005 BMW 325i, 2004-2005 BMW X3, and 2003-2005 BMW Z4. After installation, clear any stored diagnostic trouble codes and inspect for intake leaks that can affect airflow readings.
