Garrett External Wastegate GVW – 45mm / Blue

Garrett Vent | External wastegates regulate the speed of the turbocharger shaft by venting the exhaust gas around the turbocharger’s turbine stage. The CFD-optimized design maximizes flow and provides optimal boost pressure control. Advanced thermal optimization increases membrane durability. The cap design makes spring replacement and maintenance easier and more reliable across the GVW range.
