Product Description

The Turbosmart TS-0681-4102 IWG75 universal internal wastegate actuator is a versatile performance component engineered to upgrade the wastegate control on a wide variety of turbocharger setups. With a 10 PSI pre-set base spring and Turbosmart's IWG75 design, this actuator increases the effective diaphragm area for a stronger working ratio compared with many stock units, helping boost build and hold more consistently throughout the rev range. This can improve throttle response and torque delivery without drastically altering your target boost level.

Built from high-grade billet aluminum with a durable black anodized finish, the TS-0681-4102 comes equipped with a heat-resistant silicone-Nomex diaphragm and stainless steel rod for durability under demanding conditions. The M6 threaded actuator rod (approximately 140 mm long) makes it suitable for many internal wastegate turbo housings, though additional clevis brackets or hardware may be required for a custom fit. The locking collar design also allows easy spring swaps if future tuning or boost targets change, making this a great choice for custom turbo builds or performance upgrades.
