This means you get all the noise of the blow off valve whilst retaining the compatibility with the recirculation requirements of the engine management system. As a bonus we also offer the ability to convert the valve to recirculation only mode for those times when stealth running is required. This valve uses a Brass piston which utilises new sealing technology along with a variable spring preload, incorporating a ratchet type top adjuster that will allow for the positive and precise adjustment to match the valve to your engine.This is achieved by using a unique single, conical, progressive rate spring, that can allow for the retention of boost pressure over a wide adjustment range. This unique spring design also allows for unrestricted piston travel and flow volume regardless of the amount of pre-load adjustment added to the spring.
Other manufacturers' valves use cylindrical springs with adjustable pre-load, which often experience restricted piston travel and a reduction in flow volume. When we say our products are Engineered For Performance, it's not a catchy sales phrase, it's the truth. And we prove it with every product we manufacture. Note: This valve requires installing the opposite way to the original Bosch Valve. This means that the side pipe is fitted into the Turbo Intake Hose, and the base pipe connects to the hose that runs to the boost side of the turbo.In The Box: 1 x FMDVSPLTR Valve 1 x Valve Blanking Cap 1 x Instruction Booklet 1 x Forge Sticker.
