Turbo XS Racing Bypass Valve H-25 Diverter Valve not BOV
 

Turbo XS
Racing Bypass Valve H-25
"The Racing Bypass Valve Type 25 was specifically designed to replace the 1 inch (25mm) Bosch Bypass Valve used in most Volkswagen and Audi applications. The Bosch valve is prone to failure in stock application and not adequate for holding boost in "chipped" 1.8T equipped vehicles. The RBV-25 spring tension is adjustable, making it ideal for your modified vehicle.
This valve is not loud compared to an atmosphere BOV."

Was used briefly in PERFECT working Order. This is a DV not BOV, it recircluates back unused flow
