Product Details

Cardone’s New Mass Air Flow Sensor line focuses on OE-style signal tracking and controlled tolerances so the engine control module receives the airflow data it expects. That matters on turbocharged and naturally aspirated BMW applications where incorrect airflow readings can affect fuel delivery, idle quality, and drivability. Part number 86-50088 is a direct replacement option for BMW 640i Gran Coupe, 640i xDrive Gran Coupe, 640i, 640i xDrive, X4, X5, X6, 535i GT, 535i GT xDrive, X3, 535i, 535i xDrive, ActiveHybrid 5, 335i, 335i xDrive, 740i, 740Li, 740Li xDrive, ActiveHybrid 7, X1, 135i, 335i GT xDrive, 435i, 435i Gran Coupe, 435i xDrive, 435i xDrive Gran Coupe, M235i, and M235i xDrive applications listed in the fitment data.

This part cross-references BMW 13627593624 for the same application.

Common Issues It Can Address

• Hesitation during acceleration
• Stalling or unstable idle
• Poor fuel economy
• Poor engine performance
• Diagnostic trouble codes related to airflow measurement

Installation Notes and Tips

Before replacing the sensor, inspect the air filter, intake tract, wiring, and connectors for dirt, debris, cracks, moisture intrusion, or damage. Check for stored fault codes and verify the sensor element and housing are free from burn marks, contamination, or physical damage. This is a bolt-on, specific-fit component with one rectangular connector and four male terminals; confirm the connector style and mounting points match the original unit before installation.

Quality Assurance

Cardone Engineered Technology is used to help ensure the sensor follows OE output behavior and stays within strict tolerance targets for scan-tool accuracy and proper operation. The sensor is built for regular-grade service and is supplied new with an instruction sheet.
