Description
Turbosmart IWG75 Internal Wastegate Actuator – 5 PSI Black (Subaru WRX 2008)
Engineered to deliver faster boost response and superior boost stability for the 2008 Subaru Impreza WRX 2.5L Turbo (TD04).
The Turbosmart IWG75 Internal Wastegate Actuator is designed as a high-performance upgrade for the OEM Subaru WRX TD04 turbocharger. Featuring an increased working ratio compared to factory equipment, the IWG75 provides maximum boost control, eliminating premature wastegate flutter and boost drop-off at higher RPMs. Manufactured from high-grade CNC-machined billet aluminium with a high-temperature silicone Nomex diaphragm and stainless steel rod, this actuator ensures rock-solid durability and precision under extreme turbocharged conditions.
Key Features
- ☑ Optimised Working Ratio: Larger effective diaphragm area delivers increased leverage for sharper, faster boost response.
- ☑ Billet Aluminium Construction: Precision CNC-machined housing with an anodised black finish for long-lasting heat and corrosion resistance.
- ☑ Silicon Nomex Diaphragm: High-temperature reinforced design engineered to withstand severe thermal loading and boost pressure cycles.
- ☑ Unique Locking Collar System: Allows effortless spring changes and internal maintenance without full unit disassembly.
- ☑ Direct Bolt-On Fitment: Includes a vehicle-specific mounting bracket engineered directly for the 2008 WRX TD04 turbo housing.
