Throttle Body Intake Boot, BMW - E39 540i & E38 740i (1996-1998)

The rubber intake boot connects the air flow sensor with the throttle body tube on 1997-1998 E39 540i 1996-1998 E38 740i/740iL models. It's after the air filter and mass air meter so any rips or tears on the boot material will allow unfiltered and unmetered air into the engine. And since vacuum and air pressure within the engine are closely managed, any air leak can be a serious problem. 

Air leaks from a cracked intake boot can cause your E39 or E38 to run rough, poor idle, throttle surging, stumbling, hesitations, and misfires. These can be caused by other things but a leak in the intake boot is easy to check and inexpensive to fix! This is a less expensive aftermarket version of the original BMW rubber intake boot and comes with a two year warranty.

This part is listed by BMW as BMW part number 13711432410 (13-71-1-432-410) and is described as Genuine BMW Throttle Body Intake Boot.
