CTS Turbo Mercedes-Benz VTA M177 W205/C253 C63/C63S/GLC63/GLC63S AMG

CTS Turbo's vent-to-atmosphere diverter valve system is purpose-built for Mercedes-Benz M177 twin-turbo V8 applications across 2017–2021 C63, C63S, GLC63 and GLC63S AMG variants. This direct-fit VTA solution replaces the factory recirculation valves, venting compressor pressure to atmosphere during throttle lift-off. The design delivers crisper throttle transitions, eliminates compressor surge under aggressive driving conditions, and produces the unmistakable blow-off sound expected from a performance turbo setup. Manufactured from high-grade materials to withstand sustained boost environments, the kit includes all necessary hardware for straightforward installation on W205 and C253 chassis platforms.
