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.
