Idle Air Control Valve Hose, OEM - E34 525i M50NV

The rubber intake boot connects the idle control valve with the throttle body boot on the E34 525i M50 non-VANOS engine. 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 E34 525i 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 an OEM intake boot manufactured by an original supplier to BMW for this part, as well as many other engine components. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
