T9388

The T9388 is the latest addition to the DV+ range of diverter valves from GFB (Go Fast Bits). It is designed as a complete drop-in replacement for the OEM diverter valve in late-model Mercedes vehicles.

Unlike the earlier generation diverter valves manufactured by Pierburg, the newer AMG-branded OEM valves cannot be disassembled and incorporated into a DV+. Therefore, GFB developed the T9388 with a low-profile integrated solenoid as a complete replacement for both the AMG and Pierburg diverter valves, enabling a hassle-free installation with no clearance issues.

Like all valves in the DV+ range, the new T9388 delivers the following benefits over the OEM diverter valve:

• Improved boost holding
• Sharper throttle response
• Faster boost recovery after a gearshift or brief throttle lift
• Unrivalled longevity, backed by our Lifetime Warranty

Fits the following Mercedes-Benz models:

GFB Warranty

Built-in Obsolescence? Not with GFB!

We live in a throw-away society, conditioned by cheap products and frequently released new models, to expect eventual failure and discard something when it stops working or is superseded. However, pride in workmanship and our commitment to quality means that when we put our name to something, we are also staking our reputation on it.

That’s why we back our products with the best Warranty in the business! You should expect a lifetime of use from a well-engineered product, so if your GFB product fails as a result of defective materials or faulty workmanship whilst you remain the original owner, we will repair or replace it. For full warranty details, please visit the GFB Australia website.

If the fault of occurred as a result of usage outside of the terms of the warranty, or you are not the original owner, fear not, we can still help you. You should never need to throw a GFB product away, as spare parts are available and won’t cost the earth.

Tech Support: We don't have a "Tech Support" team or department. We have engineers. When you contact us through our tech support email, you will be dealing directly with the engineers who actually design GFB products. They have more experience with the product than anyone on the planet to ensure you get the right advice.
