Forge Blow Off Valve Spring Tuning Kit (FMDVTUN)
BOV Spring Tuning Kit by Forge Motorsport
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. The strongest spring is the red, followed by the blue, yellow and finally the green which is the weakest.
We normally supply our valves, unless requested differently, with a spring that will match the tension of the manufacturer's original fitment valve. However, as many owners undertake tuning modifications some may wish to re-tune the valve characteristics to suit a given application.
If you are finding that the valve is dumping more than required or you are losing boost pressure it is normally an indication that a stronger spring is required. Conversely if the valve is failing to dump it may be necessary to install a weaker spring.
