DV+ T9352 Diverter Valve

🔧 DV+ T9352 Diverter Valve

For MINI, Citroën & Peugeot 1.6 THP Applications

KEEP WHAT WORKS. REPLACE WHAT DOESN’T.

The DV+ T9352 is a direct-fit performance upgrade designed to fix the weak factory diverter valve found on many European turbo engines. Instead of replacing the entire system, GFB’s DV+ keeps the fast-acting factory solenoid and upgrades only the valve mechanism — where the real problem lies.

⚙️ HOW IT WORKS

Factory diverter valves often fail under increased boost due to their plastic internal components and slow mechanical response.

The DV+ solves this by replacing the internal valve assembly with:

• CNC-machined billet aluminium housing
• High-precision brass piston
• Optimised sealing surfaces for high boost stability

The factory ECU-controlled solenoid is retained, meaning instant electronic response is maintained, while the weak mechanical components are eliminated.

🚀 PERFORMANCE BENEFITS

• ⚡ Sharper throttle response
• 🚀 Faster boost recovery between shifts
• 🔒 Improved boost holding under load
• 🧠 Maintains OEM ECU control for seamless operation
• 💨 Eliminates boost leakage from factory valve weakness

🔬 WHY DV+ OVER FULL REPLACEMENT BOVS?

Unlike traditional aftermarket blow-off valves that replace the entire system, the DV+:

• Keeps the OEM solenoid (fastest possible actuation)
• Avoids long vacuum hose routing and extra hardware
• Requires no spring changes or ongoing rebuilds
• Installs as a direct factory replacement
• Maintains drivability with no compromise in daily use

👉 Result: faster, simpler, stronger, and more reliable than full replacement systems
