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 it offers the ability to convert the valve to recirculation only mode for those times when stealth running is required. The Hyrbid Valve is capable of 3 different setups, which are: 1.) Hybrid: Atmospheric AND Re -circulating Operation 2.) 100% Re-Circulating Mode 3.) 100% Atmospheric Mode2.

Description
XS-POWER DIVERTER VALVES For many many many applications. MUCH LIKE FORGE 007 As seen on audizine and vwvortex. This is our BLACK bypass valves. Our aluminum bypass valve is a direct replacement for the plastic valve typically found on factory turbo cars from Saab, Audi, Porsche, and VW. This valve is designed to hold more boost without leakage and also looks much better than the factory valve. It also has a higher flow rate to better protect the turbo from surge situations. The kit comes with additional springs and a shim to adjust the opening pressure, clamps, and vacuum hose. Yellow spring - 15-23 PSIBlue spring - 23-30 PSI Red spring- 30 + PSI These are also great for custom turbo builds that require a recirculated bypass system, or you can use this as a blow-off valve!11. Splitter Diverter Valve Dual Port BOV for 1.8T Audi/Volkswagen
Description
SPLITTER DIVERTER VALVE FOR 1.8T AUDI/VOLKSWAGEN A Splitter Valve can be seen as a hybrid of Blow-off Valve (BOV) and Diverter Valve because it gives a combination of vent-to-atmosphere and recirculating operation at the same time. The Splitter Valve is designed to be fully compatible with requirements of engine management systems of a wide range of turbocharged applications with metered airflow systems, while retaining the discharge noise that is favored by some enthusiasts. It also comes handy with a blanking cap to replace the venting port trumpet whenever stealth mode is preferred.12.
