  • Blow Off Valve

    Blow Off Valve

    This is a piston design bypass valve that is a direct replacement for the original fitment. This valve gives greater longevity than the diaphragm (OEM) valves, but also benefits from its ability to be fitted with different springs when the boost pressure has been increased or the engine has been modified. To ease installation the top or vacuum connection is angled.

    1 x FMDVK04SA Valve
    1 x Uprated Yellow Spring
