aFe Power 46-60068 BladeRunner Street Series Wastegate Actuator TTD5_I1GHY03

When turbo exhaust back pressure increases, the stock actuator prematurely blows off the seat, softening boost in the midrange and killing torque. With twice the diaphragm area and spring pressure of the stock Wastegate, Banks BigHead Wastegate Actuator keeps the valve seated longer and achieves a higher peak boost, sooner. At peak, BigHead opens the Wastegate and holds its position, for precise boost control that gives you crisp acceleration and more mid-range pulling power.
