If you are not content with the current Audi S6, SKN provides both performance and styling improvements able to refresh the German model.
In terms of performance, the new S6 gets a new ECU unit able to boost the output of the 4.0-liter engine to 543hp and 687Nm of torque. The additional power makes the 0-100 km/h sprint possible in 4,6 seconds with the top speed exceeding 309 km/h.

This won’t shave any seconds the sprint time but will improve the top speed by adding a new exhaust system. Last but not least, SKN provides a third kit which increases the total output to 560hp and 701Nm of torque for a 0-100 km/h acceleration in 4,5 seconds.
