Having trouble putting the power down on your Audi's 4.2L V8? BFI has the solution to your troubles! After a lengthy period of design and testing, we are proud to announce the release of our complete replacement engine mount for Audi B6, B7, and some C5 models with the 4.2L V8.


Our mount will completely replace your old, tired, hydraulic engine mount. In its factory form, the engine mount is fluid filled by Volkswagen/Audi to aid in creating a softer, cushier ride. This softness is a detriment to performance and overall longevity as the fluid within the mount can often cause premature failure. We eliminate this possibility by replacing the mount completely with our proprietary bushing and bracket/cup design. Maximizing bushing area while trying to minimize vibration where possible gives our mount the advantage of having the best ride characteristics possible from a urethane bushing mount.


Utilizing laser scanning technology - we are the first to offer a solution that gives a factory fit and finish to each mount. All bosses are matched replicas of the stock locations, and all tool clearances and specs are maintained. The use of billet aluminum instead of cast and an increased minimum thickness creates a mount that is dramatically stronger than the cast stock mount.

STAGE 1 & 2

Take your pick between our Stage 1 and our Stage 2 mounts. Stage 1 mounts come with 65a durometer bushings, and are geared towards the spirited enthusiast who wants better control over motor movement without the sacrifice of excessive vibrations. Stage 2 mounts come with 85a durometer bushings, recommended for the hardcore enthusiast who is more concerned with performance than cabin vibrations. Stage 2 is great for spirited runs and track cars, but is not recommended for daily driven vehicles. 

Our mounts can be purchased individually, or in a kit, with the kit including 2 engine mounts and 1 BFI snub mount.

Active Engine Mount Cancellation Kit

All B6, B7, and C5 models with the 4.2L V8 are equipped with active mounts and will trigger a MIL if resistors are not added. Our cancellation kit will allow you to use aftermarket engine mounts on your vehicle that is equipped with active engine mounts without seeing a CEL or error message. These are a direct plug and play application and are made right here at Black Forest Industries!
