This valve soon became the most copied and imitated in the valve marketplace.The FMDV008 turbo recirculation valve is the result of 25 years of continued experience and engineering expertise. With the reputation for innovating and manufacturing the best automotive valves in the world, you can be certain that there is currently no better replacement valve available. Forge's recirculation valve features a greater flow rate than the OEM Bosch valve, as well as a faster response time, due to its revised design. 10/10, replacement for my stock 1.8t mk4 Golf DV, build quality is over the top  Great bit of kit, well made, easy to service  I bought the FMDV008 and the quality is outstanding from the packaging to the product itself, really is a piece of quality kit, easily fitted with the simple instructions included.... and it really does improve the performance By using the associated service kit (FMDVSK), as seen below, the life of the valve can be extended, and the performance can be maintained. With a lifetime guarantee, you can be sure the valve is reliable for your car.It is fully customisable to fit your application with two uprated springs provided in the kit. Forge Motorsport's improvement on the original valve has a compact design, meaning easy fitment under the engine cover. The valve is assembled with a 25mm side pipe, and the vacuum port on the top of the valve is 6mm in sizeIn The Box:1 x FMDV008 Valve1 x Uprated Yellow Spring1 x Uprated Blue Spring1 x Cable Tie1 x 2.5mm Allen key2 x 35mm Hose Clamps1 x Instruction Booklet1 x Forge StickerComplimentary ProductsBig Gear KnobService KitIntake Pressure Compensation Valve
