The motor mount is what attaches the engine to the chassis of the car and over time the hydraulic fluid inside will leak out and the rubber becomes too soft. This leads to vibrations throughout the driveline and chassis. BMW engines are world-renowned for their smoothness and part of that is because of the engine mounts. You can restore engine and driveline smoothness by replacing motor mounts at the first sign of leakage or failure.

Urethane inserts are also available to reduce deflection and improve longevity of the stock mount. See Related Items below.

This is a Genuine BMW B58 engine mount 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.
