Astra VXR J MK6 2.0 TURBO Forge Motorsport Direct Fit Piston Blow Off Valve
Product Description
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.
