Product details
OVERVIEW
The GFB DV+ is a drop-in upgrade for the factory diverter valve on BMW's N55 turbo six. It replaces the OEM plastic valve body with a piston-style design that uses GFB's patented TMS (Timing Management System) spring to hold boost pressure without leaking, giving a faster, more consistent recirculation response than the stock unit — especially once the factory valve has worn or started to leak.
It reuses the factory electrical solenoid, so there's no wiring or tuning change required, and it bolts straight into the stock location using the factory mounting hardware.
SPECS
- Piston-style diverter valve with GFB TMS spring for consistent boost holding
- Retains and reuses the factory electrical solenoid coil — no rewiring required
- Direct bolt-in replacement using factory mounting hardware and factory port location
- Reduces valve flutter/leak that develops in the OEM plastic valve over time
- Two valve variants sold by GFB for this engine family: T9356 (general N55 applications) and T9357 (BMW M2 F87, N55B30T0)
