Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code but not always a check engine light. A misfire code may be related to an ignition coil but could be from other things as well. Sometimes a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.
This is the current replacement for some BMW 6 and 8-cylinder engines built in the late 2000s and after. BMW has made numerous changes to ignition coil part numbers in recent years but has approved this part number to work in the vehicles listed below. It's listed as a replacement coil for N20, N55, and S55 engines. In March 2015 BMW approved it for N51/N52 engines. This part number replaces the previous BMW part number 12137594937 for the cars listed below.
Sold per coil. Includes boot and connector.

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.
