The FA24 engine in the 2022+ WRX now uses an electronically controlled factory diverter in place of the pneumatic bypass valve found on all previous turbo Subaru engines. This is controlled by the ECU, and whilst it sounds like an advancement in technology, in some ways it is a step backwards. It may react to throttle closures faster than a pneumatic valve, but longevity and boost sealing is an issue with these types of valve because their valve mechanism is made entirely of moulded plastic. Importantly though, the factory electronic valve cannot open and close progressively - it's either open or shut, resulting in less than optimum throttle response and drivability. The DV+ design solves all the shortcomings of the factory electronic diverter valve, replacing the plastic valve assembly with precision CNC machined metal components, and also changes the operation method so it can open and close progressively wilst retaining electronic control. This ensures ultimate boost holding and durability, and the best possible throttle response.
Performance Diverter Valve , this valve has:
SHARPER THROTTLE RESPONSE
• FASTER BOOST RECOVERY ON GEARSHIFT
• SOLVES BOOST LEAKING ISSUES
• BUILT TO LAST
10% FASTER OPENING, 50% FASTER CLOSING THAN THE FACTORY DIVERTER
• RETAINS THE FACTORY SOLENOID FOR SEAMLESS INTEGRATION
• REPLACES PLASTIC VALVE PARTS WITH METAL FOR RELIABILITY AND STRENGTH ON STOCK OR MODIFIED ENGINES
• DIRECT-FIT REPLACEMENT WITH GFB’S TMS BENEFITS
• EXCLUSIVE “PILOT-ACTUATED” VALVE MECHANISM FOR RAPID RESPONSE AT HIGH BOOST
Solves boost leaking and reliability issues, whilst improving throttle response.
The Go Fast Bits GFB Diverter Valve DV+ is a high-performance upgrade designed specifically for the 2022 and 2023 Subaru WRX models. This performance diverter valve replaces the factory electronic diverter, which relies on plastic components and offers limited throttle response and durability. Crafted from precision CNC-machined metal, the DV+ enhances the robustness and longevity of your vehicle's boost control system. The valve features a pilot-actuated mechanism that allows for progressive opening and closing, providing sharper throttle response and more consistent boost control during gear shifts or quick throttle inputs. Designed to be a direct-fit replacement, the GFB DV+ retains the factory solenoid for seamless integration and offers significant improvements over the stock part. It opens approximately 10% faster and closes 50% quicker than the factory diverter, resulting in a more immediate and precise boost response. These enhancements help eliminate boost leaks and improve drivability, especially on modified engines where reliability is crucial. The valve’s metal construction ensures durability under high boost conditions, making it suitable for both stock and upgraded setups. Installation is straightforward, with the DV+ compatible with the existing factory mounting points and electrical connections. Whether you're looking to improve throttle response, boost recovery, or reliability, the GFB Diverter Valve DV+ delivers top-tier performance. Please note that this product is not CARB approved and requires acknowledgment of Prop 65 compliance. It is an ideal upgrade for enthusiasts aiming to optimize their Subaru WRX’s turbo system with a reliable, high-performance diverter valve that stands up to demanding driving conditions.
