Forge Motorsport FMDVTUN - BOV Valve Spring Tuning Kit FMDVTUN Grimmspeed Boost Control Solenoid - MazdaSpeed3
Now you can fine tune your Blow Off/Diverter Valve to the exact needs of your engine with this complete tuning kit.

Your valve tuning kit you will find four springs and three spacers.

The strongest spring is the red, followed by the blue, yellow and finally the green which is the weakest. The spacers enable you to fine tune the settings between two spring tensions if required.
The GrimmSpeed MazdaSpeed3 Boost Control Solenoid is designed to work with your factory computer (requires tuning). It will not reduce the life of your factory computer because it is designed to draw the same ammount of power as the factory BCS but flows better and reacts faster. It plugs in and requires no splicing or soldering of resistors. With the included bracket you can bolt it in, plug in the connector, and start tuning for fast boost response, increased boost pressure and free up lots of power. Planning on returning the car to stock? Just reverse installation.
