Product Info
Replace the compatible factory electronic diverter valves with a pair of billet VR29 valves while retaining factory electrical control. Integrated solenoids and internal pressure passages avoid separate solenoids and external reference hoses. Boost-Balance construction and a piston-face seal support sealing under boost.
TS-0223-1055 Dual Port combines recirculation with audible atmospheric discharge. TS-0223-1255 Plumb Back returns discharged air to the intake. Both packages contain two valves, six M6 fasteners and a decal; the installation guide also lists a cable tie and instruction card.
Turbosmart specifies Mercedes M177 4.0L twin-turbo engines in C, E, S, GT, G, GLC, GLE, GLS and SL class applications. Match the engine code and original valve arrangement before ordering. The class or C63 badge alone does not establish fitment for other engines. Check local requirements before choosing atmospheric venting.
