As long as the BOV has a connection on the outlet. Alot of them dont. Some have horn outlets that are cast into the body, some just have holes drilled around the outside of the body, etc...
Like I say, being a Volvo its probably got a Bosch valve in it, and the Forge 007 will go in place of the Bosch without any mods.. And it is louder. I have one set up as a bypass valve on my beetle and you can hear it every time I let off.
