CTS Turbo VTA adapters (Vent to Atmosphere) for Mercedes-Benz vehicles with the M177 engine provide a more pronounced blow-off valve sound without excessive volume.
The adapters are installed directly onto the vehicle while the factory valve remains in use. According to the manufacturer, this prevents the engine fault light (CEL) from coming on, and no software adjustment is required.
Features:
- Precisely machined aluminium
- Black anodised finish
- Quick installation
- No engine fault light (Check Engine)
Weight: 0.45 kg
