The GFB DV+ T9358 is a plug-and-play upgrade for select Mercedes-Benz, Ford, and Volvo models with electronically controlled OEM diverter valves. It retains the factory solenoid and ECU control for flawless integration.

Key Benefits

• Sharper throttle response thanks to pilot-actuated operation
• Faster boost recovery following gear changes
• Fixes boost leaking issues common with factory plastic valves
• Durable all-metal internals built for long-term reliability
• Direct-fit installation — no modifications needed

Why Choose the T9358?

GFB’s DV+ solution improves over OEM diverters by replacing fragile plastic components with robust metal parts, solving common boost leak failures—especially prevalent in vehicles with plastic-mounted diverters.

Utilizing GFB’s precision-engineered “pilot-actuation” system, the T9358 valve adjusts progressively in response to boost pressure, smoothing throttle modulation and improving control.

Installation and Build Info

• Uses the factory solenoid coil and mounting points
• Internal components made from billet aluminum and brass
• Operates reliably at boost levels up to 50 psi
• Integral design accommodates AMG- and Pierburg-type OEM valves

Installation requires minimal effort—simply swap the stock diverter valve for the T9358 and go.
