Detailed Description

Febi 47727 is a replacement mass air flow sensor hose engineered for BMW X5 models from 2001 through 2006. The hose uses NBR material, which is commonly selected for intake and emission-related rubber components because it maintains flexibility while helping preserve a secure connection. With inner diameters of 79.0 mm and 77.0 mm, this hose is sized to match the specified application and support stable airflow between components. This part cross-references BMW OE number 13 54 1 440 102 for the same application.

What It Helps Solve

• Cracked or split intake hose sections
• Loose connections at the mass air flow sensor
• Unmetered air entering the intake tract
• Air leaks that can affect drivability and engine performance
• Degraded rubber hose material from age and heat exposure

Installation Notes and Tips

Verify hose diameter and routing against the original part before installation. Inspect adjoining clamps, sensor necks, and intake tubes for wear, contamination, or damage so the new hose seals correctly. For BMW X5 service work, confirm the vehicle year and intake configuration match the listed fitment before ordering.

Quality Assurance

Febi supplies replacement components built to match specified vehicle applications, and this hose is produced to the listed dimensions and material specification for the BMW X5 platform. Part number 47727 should be matched to the vehicle identification and original hose dimensions for accurate service selection.
