19 C63 S Blow Off Valves
M177 VTA ADAPTER SYSTEM
The M177 VTA (Vent to Atmosphere) Adapters are designed and manufactured as a complete and simple bolt on solution for attaining the "blow-off" sound that many people are fond of on turbocharged vehicles with out being excessively loud or high pitched. The M177 engine comes equipped with twin electronically actuated bypass valves molded into the intercoolers that recirculate back into the airboxes for near silent operation. With the M177 VTA Adapters, there will be no check engine light as the factory valves are still used, and no tuning or ECU calibration is required.
