Product Details

Cardone’s Mass Air Flow Sensor line focuses on restoring accurate airflow signal output for engine management systems. The remanufacturing process is centered on electrical integrity, output consistency, and fitment accuracy, which matters on BMW platforms where the MAF sensor directly affects fuel delivery and drivability. Part number 74-10055 is a remanufactured replacement for select BMW models and cross-references BMW 13621438871 and 13627567451 for the same application.

What It Helps Address

• Hesitation during acceleration
• Stalling or unstable idle
• Poor fuel economy
• Poor engine performance
• Faulty airflow signal readings in engine management diagnostics

Installation Notes

Inspect the air filter, intake tract, connectors, and wiring before installing the replacement sensor. Dirt, debris, moisture intrusion, cracked ducts, loose connectors, or damaged wiring can cause repeat failure. Verify the air passages are clear and confirm the mounting points and electrical connection are clean and secure.

Quality Assurance

Each unit is tested with automated computer equipment to confirm function and reliability, and on-car validation routines are used to verify form, fit, durability, and performance requirements. The remanufacturing process also reduces energy and raw material use compared with producing a new part.
