Stainless Diesel Spring Wastegate S300 Turbos

****Free shipping to lower 48****

The sole job of the spring wastegate actuator, is to act as a pressure relief valve that controls the turbocharger boost output. The main parts of an actuator are the spring and adjusting bolt, the spring holds the wastegate shut until the turbo is delivering a predetermined boost level and then opens, allowing the exhaust gas to escape and slow the turbine. This style of actuator is operated by drive pressure. It is more accurate than the old can-style actuators. When setting boost pressures in Twin Turbo Kits, this actuator is 'far & above' the old can-style' actuators.

This spring gate comes FREE with any Twin Piping Kit.

****Fits all S300 based turbos like II phat shafts, BD Super B, Special or any other S300 style turbo.
