This valve is a direct fit for the WORKS Stage 1 and Stage 2 Tuner Turbo Kits for the BRZ and FR-S.The Splitter is a truly remarkable valve that gives a combination of
blow off and recirculation valve operation, all at the same time, and
has been specifically designed for the many turbo engined applications
that operate metered airflow management systems. 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: In the WORKS BRZ/FR-S Turbo Kits, this valve requires being installed 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.
