Volvo 440 1987-1997 TURBOSMART 25mm Uprated Dual Port Dump Valve BOV
Dual outlet-type BOV. Dual Port vents both to the atmosphere and back into the air intake. Ports with sequential timing allow quieter operation during normal driving, while getting all the benefits of a vent-to-atmosphere BOV under race conditions. Easily converted to a full atmospheric or full bypass unit by using supplied port blanking plug.
Please note; that for twin-turbo applications, such as the Audi S4 2.7L (B5) 97-01, this will require two valves.
Port Blanking Plug, Pink Spring Rated -24 to -14 InHg (installed).
