BMW E36 - Brake duct air intake - M bumpers only
Set of 2 replacement brake duct air intakes for the BMW E36 front bumper cooling system, replacing OEM 51712233361.
Description
This left and right set (driver and passenger side) restores proper airflow to the braking system on vehicles equipped with the M3 or M-technic front bumper. The ducts feature a 2.5-inch (65 mm) outer diameter (OD) outlet. They can be routed directly for enhanced brake cooling or repurposed as a cold air intake feed.
Replacing broken or missing factory ducts prevents brake fade during heavy use. This set directly replaces OEM 51712233361 and 51712233362, ensuring an exact fit in the factory bumper cutouts.
