This part is listed by BMW as BMW part number 13908665249 (13 90 8 665 249) and is described as the fuel tank breather evap hose on top of the intake manifold on 2019+ B58C and B58D engines. This hose runs from the the manifold itself near the throttle body to the fuel system breather valve on top to the manifold. The evap (evaporative) emissions system keeps fuel vapors contained within the engine or fuel system so any leak is a serious emissions fault. These hoses have plastic connectors that often fail, break, or crack when disconnected so it's a good idea to have a new replacement on hand if you plan to remove one.
This is a Genuine BMW B58 evap hose with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
