Fitting without any modification to the M133 engine of the Mercedes CLA 45 / A45 AMG W176 381, this Turbosmart Kompact Dual Port dump valve features a hybrid structure with an internal piston adjustable in stiffness, operating quietly on low boost, avoiding unwanted attention, but vents to atmosphere on high boost in order to enjoy the 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 !
