GFB DV+ T9358 Diverter Valve Upgrade for Mercedes-AMG CLA45 & GLA45 (2016–2019)

The GFB DV+ T9358 is a direct bolt-on diverter valve upgrade for the Mercedes-AMG CLA45 & GLA45 (2.0L turbo, 2016–2019 facelift). It replaces the failure-prone factory plastic internals with a billet aluminum body and brass piston for sharper throttle response, faster boost recovery, and OEM-level reliability — no tuning or spacers required. Part number T9358.

Why Upgrade?

• DV+ replaces only the weak components — no spacers or tuning required.
• Billet aluminum body + brass piston for superior sealing and durability.
