The standard factory fitted Bosch valve was and still is prone to failure of the rubber diaphragm inside, leading to a boost leak.

20 years ago, Forge Motorsport recognised this common failing and developed an aluminum two piece replacement recirculation valve, utilising an aluminum piston as a replacement for Bosch plastic valve, (originally the FMCL007P). 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.
