Kompact Shortie Dual Port Mercedes AMG C63 M178 Bi-Turbo

Turbosmart’s Kompact valve kit has been developed as a direct plug-and-play solution for the new C63 AMG. Despite its high-performance intentions, the Mercedes’ standard bypass valves are plastic units that bleed boost and struggle to cope with the pressure, particularly in tuned vehicles.
