This part is listed by BMW as BMW part number 31336798834 (31 33 6 798 834) and is described as the front rubber spring pad on top of the spring in the strut assembly. It isolates and cups the spring as it sits on the strut and is important to keep clunks and thumps to a minimum when going over bumps.
This is a Genuine BMW front spring pad 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.
