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, and GFB has TWO high-performance replacement options!
Both offer the same performance benefits over the factory diverter valve:
Sharper throttle response Faster boost recovery after gearshift or brief throttle lift Improved boost holding Unrivalled longevity, backed by our Lifetime Warranty
Where they differ is the ease of installation and the price:
T9383 DV+ Supplied as a complete unit with an integrated solenoid Does not require disassembly of the factory diverter valve Can easily be returned to stock Choose this valve if you plan to remove your mods before having your car serviced RRP $250 T9369 DV+ Requires disassembly of the factory diverter valve Replaces factory valve mechanism, re-uses the solenoid coil There is a possibility that you may not be able to return the diverter valve back to stock after installation. This is due to the risk of damaging the fragile plastic of the factory valve mechanism that is removed to install the T9369 DV+. This does not impact the solenoid or DV+ installation. Choose this valve if you don’t plan to return the car to stock! RRP $169
Factory electronic diverter valves have been around since 2006 (particularly on European engines), and on the surface it sounds like an advancement in technology, but in reality it’s a step backwards in performance and reliability.
Electronic diverters may react to throttle closures faster than a pneumatic valve, but longevity and boost sealing is an issue 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 patented DV+ design has been proven since 2013, and regardless of which type you choose, it solves ALL the performance and reliability shortcomings of the factory electronic diverter valve.

What makes GFB blowoff valves different and better?
Our new TMS Turbo Management System don't throw your BOOST away but INCREASES IT BY up to 40%. GFB's Turbo Management System (TMS) parts offer multiple performance benefits over factory diverter valves. We looked at the concept named ‘blowoff valve’ and took this to a whole new level! Basically the main benefits are:
MORE POWER - BETTER RESPONSE - BETTER DRIVE ABILITY - GET THE SOUND OR NOT.
How to choose a BOV
With the vast range of GFB blow-off valves, questions rise 'Which blow-off valve is the best?' and 'Which blow-off valve should I use?'
The first question is easy to answer: There isn't actually a 'best' in terms of quality. All GFB blow-off valves use the same high-quality internal components. So, provided the right BOV is fitted for your particular vehicle, they all offer the same performance benefits of improved throttle response and reduced lag. The real question is: How do you select the valve for you?
The first step to decide on 'your' BOV, is whether or not you want to hear it, and if so, how much? The following chart lists the “noise ratings” of our blow-off valve range. The final decision will then be based on how much control you want over the blow-off volume level.
GFB boost controllers use a more consistent needle-valve bleed system, which brings boost on just as fast as any ball-and-spring system, and generally more quickly than a factory boost control system. On the productpages you can find a comparison of the GFB controller to other major brands, guess who wins this standoff? GFB!
A GFB boost controller will give you the added benefit of not only being able to adjust the peak boost level, but in most cases will bring the boost on earlier, resulting in more power throughout the rev range.
The reduction in rotating inertia (we've removed about 2kg by using 6061 T6 aluminum billet) means that the engine can accelerate much quicker during the times it is making very little power before the turbo spools up. The result is better drive ability off-boost and better acceleration, which is especially useful for those with large turbos that only make power in the upper rev range. The smaller size of the crank pulley under-drives the power robbing accessories so that the upper end of the rev range is less burdened, while still allowing them to operate properly.
Short Shift Kits
The GFB Short Shifter is the same height as the factory shifter, it is the actual distance that the gear stick moves between gears that reduced.
Very simple to install. All of the installation is done from inside the car, without having to jack it up and crawl around underneath. Only a few basic hand tools are required, and the necessary hex keys are supplied.
The maximum throw reduction varies for different models. Early WRXs had a particularly long throw, so the maximum reduction with the GFB kit is around 50%, whilst on later models it is closer to 40%. In either case, it is possible to reduce the distance per gate to about 30mm. Whilst it can go shorter, the shifting force becomes too great for comfort, and some of the shift feel is lost.
