The T9488 VTA is a performance blow-off valve solution for Mercedes vehicles.
If you want sound with your performance (or performance with your sound!), GFBs T9488 VTA delivers!
By combining atmosphere venting with the proven performance benefits of our ground-breaking DV+, the VTA delivers an aggressive blow-off sound, improved throttle response, as well as superior boost holding and reliability.
With its low-profile integrated solenoid and compact design, installing the T9488 is a breeze. Just swap out your factory diverter valve with the VTA, and youre good to go!
Key features and benefits:
Why choose a VTA over a BOV spacer? Whilst BOV spacers might offer a cheap way to get a blow-off sound, they fail to tackle the fundamental performance and reliability issues associated with the OEM diverter valve all they do is redirect the vented air. The VTA offers more than just sound. By replacing the OEM diverter valve you also get enhanced performance and reliability.
Reliable Boost Holding.
Despite some improvements in reliability by the latest generation of OEM diverter valves, the performance trade-offs remain. There is no escaping the fact that the moulded plastic valve mechanism of the OEM valve cannot reliably seal boost pressure. The VTAs CNC-machined aluminium and brass valve components, combined with a Viton face seal ensure reliable boost holding even up to 50psi.
Sharper Throttle Response, Faster Boost Recovery.
OEM electronic diverter valves are binary in operation theyre either open or shut. Your throttle, however, isnt. When you make small throttle adjustments, the binary operation of the factory diverter results in abrupt changes in power delivery, which is the very definition of poor throttle response. GFBs pilot actuation system allows the VTAs piston to open and close progressively, thereby smoothing the power delivery during throttle modulation, and ultimately improving throttle response.
Unrivalled longevity, backed by GFBs Lifetime Warranty.
The combination of precision manufacturing, attention to detail, and robust materials means the VTA will last a lifetime. So does the warranty!
