GFB VTA T9488 blow-off valve - Mercedes-Benz models

The GFB VTA T9488 is a high-performance VTA (Vent To Atmosphere) blow-off valve designed to improve boost pressure relief and throttle response in turbocharged Mercedes-Benz models.

The VTA valve releases boost pressure directly to the atmosphere when the throttle is closed, which reduces the back pressure of the supercharger and at the same time produces a clearly audible, sporty exhaust sound.

Efficient and fast decompression

Factory valves are often designed with comfort and noise control in mind. The GFB VTA T9488 provides faster and more precise boost pressure release, helping to protect the supercharger and improve throttle response feel, especially during dynamic driving.

Result:

  • Faster compressor depressurization

  • Better throttle response feel

  • Reduced supercharger load

  • Clear and sporty blow-off sound

Features

  • Vent To Atmosphere (VTA) construction

  • Fast and efficient decompression

  • Improves throttle response feel

  • Reduces stress on the supercharger when the throttle is closed

  • Durable and precisely machined construction

  • Plug & Play installation to replace the original valve

A sporty upgrade to performance and sound

The GFB VTA T9488 is an excellent choice for the driver who wants to:

  • Sharper driving feel

  • More efficient boost pressure control

  • A clearly audible blow-off sound

  • A reliable and long-lasting valve solution

The valve is particularly suitable for hobby and tuning use, where sound and response play a key role.
