This makes the BMW F10 F11 LCI B47 Air Intake Duct an essential component for post-collision repairs, replacement of damaged body parts, or restoring factory airflow after modifications.

The offered duct comes from the BMW OE line, meaning it retains the factory geometry, mounting points, and compatibility with the hardware used in LCI versions with the B47 engine. In practice, this translates to:

• precise fitment with engine bay and body components,
• no need for modifications during installation in appropriate F10/F11 versions,
• maintaining factory airflow characteristics.

A used OEM part is particularly beneficial for repairs where maintaining the original design and intake system operating parameters is crucial.
