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

GFB DV+ T9358 Diverter Valve for Mercedes-AMG 2.0T (CLA45 / GLA45)

The GFB DV+ T9358 is a direct-fit diverter valve upgrade for Mercedes-AMG 2.0L turbo engines, engineered for the CLA45 AMG and GLA45 AMG. It replaces failure-prone factory internals with precision billet aluminum and a brass piston while retaining the OEM solenoid for full ECU control. The result is sharper throttle response, faster boost recovery, and consistent boost pressure—ideal for stock or tuned AMG applications.

Often confused with a blow-off valve (BOV), a diverter valve recirculates boost back into the intake for smoother drivability, quieter operation, and OEM reliability—making it the correct upgrade for modern Mercedes-AMG turbo engines.

• Sharper throttle response
• Improved boost recovery between shifts
• Eliminates common factory boost leaks
• OEM solenoid retained
• Billet aluminum & brass piston
• No tuning or resistors required

CLA45 / GLA45 AMG Compatibility (U.S.)

Fits U.S.-market facelift CLA45 and GLA45 AMG models listed above. Always verify engine code and factory diverter configuration before ordering.

Why Upgrade the Factory CLA45 / GLA45 Diverter Valve?

• Factory diverter valves use plastic internals that can leak under higher boost
• DV+ replaces only the weak components—no spacers or adapters
• Pilot-actuated design responds progressively to boost pressure
• Helps reduce turbo flutter and compressor surge under lift

Unlike spacer-style solutions, the DV+ improves sealing and response while preserving factory ECU logic and drivability.

What You’ll Notice on the Road

• Immediate throttle and boost response
• Smoother, more consistent acceleration
• Stable boost pressure on stock or tuned setups

FAQ

• Is this a blow-off valve?
  No. Modern Mercedes-AMG turbo engines use a diverter valve that recirculates boost for smoother drivability and reliability. The DV+ improves performance without loud vent-to-atmosphere noise.

Upgrade your Mercedes-AMG CLA45 or GLA45 with the GFB DV+ T9358 for OEM-level fitment, sharper response, and reliable boost control.
