The rubber intake boot connects the air flow sensor with the throttle body on the 1989 E30 318i/318is/318ic M42 (1989+). This rubber air boot is after the air filter and mass air meter, so any cracks, 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, an air leak can be a serious problem. 

Air leaks from a cracked intake boot can cause your E30 318i/318is 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 the Genuine BMW rubber intake boot and comes with a two year warranty.
