This genuine BMW air intake duct (OEM 7642406) is a used part salvaged from a donor vehicle. Also known as an intake tube, it delivers filtered air to the 0.6L 647cc two-cylinder range-extender (REX) engine found in the BMW i3 and i3s. Over time, the plastic can crack or the connections loosen, causing unmetered air entry and rough idle; a direct replacement restores proper airflow.
