Mosselman's Stage 2 MSL Upgraded Turbocharger Set for the S55 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 and 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 and the other high-performance parts. 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.
