This BMW brake cooling air duct, OEM part number 7378073, is a genuine used unit originally installed on the front left side. It channels airflow directly to the brake components to help reduce heat buildup during repeated stops. A cracked or missing duct can lead to accelerated brake fade, especially under spirited driving or towing. This part comes from a donor X3 or X4 equipped with any of the 2.0L diesel or gas turbocharged four-cylinder engines, or the 3.0L turbocharged inline-six.
