Description

The CTS Turbo VTA M177 adapter system is a precision-machined aluminum component with a black anodized finish, designed for Mercedes-Benz M177 engines. This bolt-on solution provides the desirable blow-off valve sound without being overly loud, enhancing the auditory experience of your vehicle. A key benefit of this adapter system is that it will not trigger a Check Engine Light (CEL), as it works in conjunction with the vehicle's OEM diverter valve. Furthermore, no engine tuning is required for its operation, simplifying the upgrade process. This includes the 2017-2021 Mercedes-Benz E63/E63S (W213), the 2018-2021 Mercedes-Benz S63 (W222/C217), the 2019-2020 G63 AMG (W463), and the 2019-2023 AMG GT 63/AMG GT 63S (X290).
