GFB DV+ T9358 Diverter Valve Upgrade for Mercedes M270 (CLA250 / GLA250)

GFB DV+ T9358 Diverter Valve for Mercedes M270

The GFB DV+ T9358 is a direct-fit diverter valve upgrade for Mercedes M270 engines, designed specifically for the CLA250 and GLA250. It replaces failure-prone factory internals with precision billet aluminum and a brass piston, while retaining the OEM solenoid for factory ECU control. The result is faster boost response, cleaner shifts, and consistent boost pressure—perfect for daily-driven or lightly tuned cars.

• 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

M270 Platform Compatibility (U.S.)

Fits U.S.-market M270-equipped vehicles listed above. Always verify engine code and factory diverter configuration before ordering.

Why Upgrade the Factory M270 Diverter Valve?

• Factory valves rely on plastic internals that can leak under 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 without altering ECU logic or drivability.

What You’ll Notice on the Road

• Crisper throttle response in Sport and Comfort modes
• Smoother, more consistent acceleration
• More stable boost on stock or Stage 1 tunes
