CTS Turbo is proud to announce our new Vent to Atmosphere Adapters for Mercedes-Benz M177 C63/C63S/GLC63/GLC63S. \n \nThese are a bolt on solution to achieve that blow-off valve sound but without it being too loud. \n \nThere will be no CEL since the factory valve is still being used and no tuning is required. \n
