CTS Turbo is proud to announce our new Vent to Atmosphere Adapters for Mercedes-Benz M177 W213/W222/X290 E63/E63S/S63/G63/AMG GT63/AMG GT63S.
These are a bolt-on solution to achieve that blow-off valve sound, but without being too loud.
There will be no CEL since the OEM Diverter Valve is still being used and no tuning is required.
