GFB VTA Blow Off Valve T9488 for Select Mercedes-Benz 2014-2024 (2.0T)

Fits select 2014-2024 Mercedes-Benz models including AMG GT, C300, C63 AMG S, CLA250, CLA35/45 AMG, E250, E300, E63 AMG S, G63 AMG, GLA250, GLC300, GLC43/63 AMG, and S63 AMG (2.0T).

The GFB VTA (Vent to Atmosphere) T9488 combines an aggressive blow-off sound with the technical performance of GFB's DV+ series. Designed to replace the factory-installed electronic diverter valve, this unit solves common issues with boost leakage and solenoid failure. While OE valves often use plastic components and weak springs, the VTA utilizes a precision-machined billet housing and a high-performance brass piston to ensure superior boost holding and reliability under pressure.

Installation is a direct bolt-on process thanks to the integrated low-profile solenoid, which is specifically engineered to fit within the tight packaging of modern Mercedes engine bays. By retaining the factory ECU control but upgrading the mechanical internals, the T9488 delivers sharper throttle response and faster boost recovery without triggering fault codes.
