Looking for more than just chiptuning? Our MSL Turbocharger for the N55 engine offers a huge boost in performance. By increasing the airflow and reducing backpressure, these turbos increase performance levels significantly without sacrificing reliability. To ensure maximum compatibility, they’re based on OEM quality turbos, but with several components of our own design to ensure the highest quality reliability. 

Thanks to their OEM origins, the MSL Turbochargers are easy to install and require no additional modification. Of course, they work beautifully with our ECU Remaps, iTronic Engine Controllers and the other high-performance parts in our line-up. Each MSL Turbocharger is manufactured according to Poka Yoke and ISO standards on the in-house production line. They are subjected to rigorous quality control and VSR reports and come with a limited 1-year warranty.
