GFB 5556 DV+ Performance Diverter Valve Direct-Fit Replacement

The GFB (Go Fast Bits) DV+ Diverter Valve is a direct-fit, performance-oriented replacement for the factory diverter valve on turbocharged vehicles. Engineered by GFB in Australia under ISO 9001 quality standards, the DV+ targets the root cause of poor throttle response and boost leaks — the weak plastic valve mechanism found in most OEM diverter valves — and replaces it with precision-machined metal components built to last.

How It Works:

The factory solenoid coil is retained, allowing the engine ECU to maintain full control over valve operation. GFB's exclusive pilot-actuated valve mechanism and TMS (Turbo Management System) technology allow the DV+ to operate progressively in response to boost pressure, rather than simply snapping fully open or fully closed like the OEM unit. The result is a valve that seals reliably under boost and vents precisely when needed — delivering sharper response and faster boost recovery.

Key Features:

• Up to 50% faster closing than the factory diverter valve for superior boost holding
• Up to 10% faster opening for immediate pressure relief when needed
• Returns engine to peak boost up to 30% faster on gearshift compared to OEM
• Anodized billet aluminum housing with a brass piston machined to exacting tolerances
• Viton face seal on the piston for a reliable, long-lasting boost seal
• Retains the factory solenoid coil for seamless ECU integration — no tuning required
• Replaces weak plastic OEM valve parts with metal for reliability on stock and modified engines
• Eliminates boost leaking issues caused by worn or failed factory diverter valves
• No spring adjustment or rebuild kits required — pressure-balancing design holds boost regardless of spring setting
• Manufactured in Australia to ISO 9001 quality standards
• Backed by GFB's Lifetime Warranty

The GFB DV+ is a purely performance-focused upgrade that works within your factory boost control system. Whether you're running a stock tune or a modified setup, the DV+ delivers sharper throttle response, faster boost recovery, and the long-term reliability that OEM plastic valves simply cannot provide.
