Inden Design first released their tuning package for the Mercedes-Benz SLS AMG back in January of this year. Not feeling that their hard work had been noticed enough, they called upon the services of German model Katja Runiello to stand beside their incredible creation and add some sex appeal to the "Flyer" package. Inden's tuning package for the SLS AMG includes a power boost of its 6.2-liter V8 engine.

Output has been cranked up from 571hp to 623hp thanks to the use of a new exhaust system complete with sportskats and manifold along with a software upgrade. New gloss black wheels measuring at 21-inches have been added, wrapped in Continental Sport Contact high-performance rubbers.
