Managing boost pressure with absolute precision is critical when pushing the 4.4-litre TwinPower turbo engine to its limits. The factory plastic diverter valves are notoriously prone to leaking under increased boost pressure, leading to sluggish response and lost power. Upgrading your hot-V forced induction system with high-performance diverter valves and heavy-duty actuators ensures stable pressure holding and rapid release during lightning-fast M DCT gear changes. Optimize your S63 setup with specialized boost control products to prevent boost leaks, eliminate damaging compressor surge, and guarantee immediate, crisp throttle response whenever you demand power.
