This kit is designed to fit any M113K AMG engine and includes our tried-and-true M113K ECU Calibration. It replaces the problematic OEM crank dampener with a brand-new OEM unit featuring a 5-axis CNC precision-machined ring, perfectly balanced and welded for proven performance gains.
 
For optimal results, we recommend pairing this upgrade with cooling modifications such as an intercooler pump, split cooling setup, or heat exchanger to enhance performance and reliability.”
