BMW Engine Parts for BMW 4 Series G22 (2021+)

From the factory, all BMWs utilize soft rubber or fluid-filled engine mounts. Not only are these mounts prone to degradation, they also allow ample movement of the drivetrain. This translates to looseness in your driveline, commonly associated with missed shifts and a generally isolated feeling.

To improve upon this issue, Black Forest Industries designed these upgraded mounts from the ground up. Their stage one mounts feature a proprietary 85A durometer bushing and bracket/cup design. Maximizing bushing area while minimizing vibration gives this mount the advantage of having the best ride characteristics possible from a urethane mount.

Features:

Perfect fit: Utilizing laser-scanning technology permits seamless integration with the factory engine mount arms. Quality tooling: All bosses are matched replicas with stock locations, and all tool clearances and specs are maintained. Heavy-duty construction: The use of billet aluminum instead of cast creates a mount that is dramatically stronger than its factory cast-construction counterpart. Performance design: 85A durometer bushings are geared toward the spirited driving enthusiast who doesn't mind increasing NVH. Choose BFI Stage 2 for a quality mount that eliminates drivetrain movement.

Note: Stage 2 mounts increase NVH. Therefore, these mounts are not intended to be used on daily driven vehicles.
