Description
This is a genuine BMW intake pipe with air mass sensor provision for BMW E87, E90 and E91 320d models with the N47 diesel engine. The primary OEM number is 11618506359. It is part of the intake and charge-air path, linking airflow components before the engine receives a measured, controlled air supply.
Its job is to route intake air correctly through the system while supporting accurate air-mass measurement for engine management. On diesel BMW applications, this component helps maintain proper airflow readings, stable engine response and efficient combustion, which are all important for performance, emissions control and smooth running.
Common signs of a faulty unit include air leaks, poor throttle response, reduced power, uneven running, fault codes related to air mass or intake pressure, and increased smoke under load. Cracks, distorted sealing areas or sensor mounting damage can all affect airflow accuracy and drivability.
This is a used original part removed from a vehicle and tested before sale. Match 11618506359 exactly before ordering. Professional installation is recommended, and seals, clips or connected sensor components should be inspected during fitting. Coding, programming or adaptation may be required where applicable after installation.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
