Does anybody know what mm the port where the recirculating diverter valve dumps the charge-air back into the air intake system is? I am looking to replace my malfunctioning stock diverter valve (BOV) with a Dual Piston Ram Dump Valve from Forge which eliminates the recirculation of charge-air leaving me to plug the port where the hose is supposed to connect to the intake piping. Forge sells the plugs I just don't know what mm I need, and I would measure it butI am looking to pick the parts up while I am in the states and the Volvo isstill inGermany.

Any help is appriciated!
