Torque Solution 02-07 Subaru WRX / 04-21 Subaru STI HD Cast Aluminum 2.4in Hard Turbo Inlet
The Torque Solution HD Cast Aluminum 2.4in Hard Turbo Inlet replaces the factory plastic inlet on 2002-2007 Subaru WRX and 2004-2021 STI models. This direct bolt-on part delivers increased airflow to the turbo compressor for faster spool times and sharper throttle response under boost. Built to handle high-pressure applications it ensures consistent performance on street or track.
Key Features

- 2.4 Inch Diameter: Matches turbo compressor inlet size for maximum airflow volume over restrictive OEM design.
- Smooth Cast Internal Bore: Eliminates flow disruptions for efficient air delivery and reduced turbulence to the turbo.
- Black Anodized Finish: Provides corrosion resistance and heat dissipation in engine bay conditions.
- Direct Bolt-On Design: Includes silicone O-ring seal and stainless hardware for hassle-free installation.
Product Notes
- Compatible with TD04 TD05 VF39 VF48 and IHI VF-series turbos found on WRX and STI models.
