The GFB VTA is a vent-to-atmosphere blow off valve that adds an aggressive blow-off sound while sharpening throttle response and boost recovery. T9488 is a direct bolt-on for most Mercedes turbo petrol engines including the CLA35 AMG 2.0T. Its integrated low-profile solenoid retains factory ECU control. Note that twin-turbo engines typically require two valves.
