Fitting without any modification to the 2.0T engine of the Opel Astra H OPC, this Turbosmart Kompact Dual Port dump valve features a hybrid structure operating quietly on low boost, avoiding unwanted attention, but vents to atmosphere on high boost for that sought-after Blow-Off Valve sound. Offering reliability and responsiveness at any level of preparation, this high performance dump valve will bring a clear improvement in terms of response time, but also an aggressive dumping sound under full load and comfortable at low rpm !
