Blow Off Valve Springs

If you continue to add go fast parts to your vehicle, then you may be over-boosting the limits of your blow off valve spring. RallySport Direct carries a great selection ob blow off valve springs for those of you who have vehicles equipped with Tial, Turbosmart, Alta, and Go Fast Bits blow off valve springs. Blow off valve spring will open after a certain amount of PSI and if you are running big horsepower, then you could be causing a premature boost leak with a weak spring under boost. If your spring is too strong, then the blow off valve won't open and can cause over-boosting issues. 

Choose from a great selection of blow off valve springs to suit your current setup. These will come in different color combinations to reveal what PSI that they're rated at.
