034 Motorsport Motor Mount, Street Density, C7/C7.5 Audi S6/S7/RS7 and D4 A8/S8 4.0T

PRODUCT DESCRIPTION:

034Motorsport Street Density Motor Mounts are the new standard in comfort and performance. These mounts are redesigned with performance in mind, and manufactured from high-durometer rubber for increased performance and durability, without sacrificing comfort. Street Density Motor Mounts are optimized void-free and fluid-free, eliminating the slop and the possibility of leakage and collapse associated with the factory mounts. The mount bodies are made from high-quality cast aluminum using OEM production techniques and employ emulators to replicate the electronics of the factory motor mounts for plug-and-play installation. This ensures MIL-free operation for cars equipped with active motor mounts.

Street Density Motor Mounts are manufactured from high-durometer rubber instead of polyurethane for a number of reasons. While vulcanized rubber mounts are more expensive to prototype due to the complexity of manufacturing and high initial tooling costs, rubber is inherently better than polyurethane as a damping medium for mounts and bushings. Rubber is able to deal with stress under both tension and compression, while polyurethane mounts rely on the damping medium to be effective only under compression. Rubber is also excellent in shear, where polyurethane is ineffective, making it ideal for applications that apply a shear force to the bushing during articulation. Rubber does not pack and wear like polyurethane does, which ultimately results in a long-lasting part with consistent performance and comfort.

While factory motor mounts will wear and tear prematurely, 034Motorsport Street Density Motor Mounts are reliable for stock and upgraded power levels.

Note: While no visible error codes or check engine light (CEL) will be shown on the dashboard, it is possible that some vehicles may have a "soft code" when scanned. There is no cause for concern with this code, as your car will function without issue.

NVH Levels: Low - Mild

NVH is the measurement of how much noise, vibration, & harshness gets transmitted into the cabin of your vehicle. Based on user feedback, 034Motorsport Motor Mounts transfer low to mild amounts of NVH to the cabin. We recommend giving the Density Line Mounts at least 250 miles to break in after installation. NVH is subjective, so some users may find NVH to be increased or decreased from our rating. If you are experiencing higher than quoted NVH with this product, please evaluate the installation to ensure to components are touching each other and email techsupport@034motorsport.com for further assistance.

Please Note: NVH will be prevalent when vehicles go into cylinder-on-demand (COD) mode.
