The ECS Heavy-Duty engine snub-mount is just the first of many new and innovative products being released by ECS Tuning for Audi's new B7 A4. The ECS snub-mount is cast from high strength Polyurethane which greatly reduces drivetrain and engine movement under heave acceleration, deceleration and shifting. After testing several degrees of hardness, it was determined that 88A provided a significant improvement in shifting accuracy without any additional cabin vibration.
