GFB Expands DV+ Range for European Vehicles

GFB is proud to introduce an extended DV+ range, offering a direct-fit solution for the factory diverter valve used in a wide range of European vehicles. This innovative product is engineered to enhance both performance and reliability.

Key Features:

• Utilizes the factory solenoid coil for seamless integration
• Replaces weak plastic valve components with robust metal parts, ensuring durability and strength, even on chipped engines
• Direct-fit replacement with GFB's TMS benefits, simplifying installation
• Features an exclusive "pilot-actuated" valve mechanism for rapid response during high boost conditions

Specifically designed for the N14 MINI Cooper S/ JCW Engine, GFB's DV+ is the ideal solution to optimize your vehicle's diverter valve.

Optimize your BMW's performance by adjusting your diverter or blow-off valve using this kit containing four springs with varying strengths. When noticing excessive pressure release or a drop in boost pressure, it's an indicator that a stronger spring might be necessary.

Important Notes:

• Fitting a stronger spring won't increase boost pressure unless there's a pressure loss.
• Installing an excessively strong spring may damage the turbocharger if it restricts the valve's operation.

Valve Spring Color Coding:

• Green: Suitable for 5-15 PSI
• Yellow: Ideal for 15-23 PSI
• Blue: Designed for 23-30 PSI
• Red: Suitable for 30+ PSI
