The TurboSmart Dual Port Blow Off Valve  is three BOVs in one. The Dual Port can be configured to vent to the atmosphere (VTA), recirculate into the air intake or BOTH! This blow off valve is also adjustable allowing you to tune the BOV to meet the needs of your car. This is done simply by a turn of the hand. No tools are required to adjust the stiffness of the blow off valve. The recommended setup for TurboSmart Blow Off Valve kit on the MAZDASPEED 3 is the Dual Port option. Using the Dual Port setup, the BOV will recirculate under low boost driving. During high boost situations, the BOV will VTA and recirculate into the intake.
