Product Details

Cardone’s Mass Air Flow Sensor line focuses on restoring proper airflow measurement so the engine control system can calculate fuel delivery accurately. This remanufactured unit is built to maintain specific tolerances, helping the vehicle read airflow data consistently and respond smoothly under changing driving conditions. The part number 74-51011 is a direct-fit solution for select BMW M5, M6, Z4, M3, and Z3 engine management applications.

This part cross-references BMW OE numbers 13627830359 and 13627839014 for the same application.

What It Helps Fix

• Hesitation during acceleration
• Stalling or rough idle
• Poor fuel economy
• Poor engine performance
• Intermittent scan tool readings caused by sensor output issues

Installation Notes

Before installing the replacement sensor, inspect the air filter, intake tract, connectors, and wiring for dirt, debris, looseness, cracks, or damage. Over-voltage, shorted wiring, moisture intrusion, air intake obstructions, and oil or fuel fumes can contribute to sensor failure, so correcting the root cause helps protect the replacement unit. Verify the sensor element and surrounding intake components are clean and undamaged before final assembly.

Quality Assurance

Each sensor is tested with automated computer equipment, and Cardone uses on-car validation routines to confirm fit and performance requirements. The remanufacturing process also reuses existing core materials, reducing energy and raw material demand compared with manufacturing a new part.
