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 everyday driving while getting all the benefits of a vent-to-atmosphere BOV under race conditions. They are easily converted to a complete atmospheric or full bypass unit by using supplied port blanking plug.
Fits all Mitsubishi Evolution models (running stock or close to stock boost levels) as well as the Colt/Lancer Ralliart and 3000GT/GTO. It also fits Liberty/Legacy GT (MY09-current).
It can also be used in universal applications where 34mm ID piping is being used.
