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
- HD Cast Aluminum Construction: A356-T6 aluminum casting resists boost pressures up to 40 PSI without flexing or cracking unlike stock plastic.
- 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.
- Inspect turbo compressor outlet gasket during install for optimal sealing.
- Packages in protective foam insert within sturdy cardboard box.
Installation Notes

Fabrication
Fabrication parts and materials provide the raw components needed to build, repair, and modify custom exhaust systems, turbocharger plumbing, intercooler piping, fuel system lines, oil routing, and engine bay heat management on performance and competition vehicles. Stainless steel tubing, titanium tubing, aluminum charge piping, mandrel bends, pie cuts, flanges, merge collectors, V-band clamps, O2 sensor bungs, AN fittings, PTFE hose kits, braided fuel and oil lines, heat shields, and welding supplies are the backbone of any serious custom fabrication project.

Brands including Vibrant Performance, Ticon Industries, Stainless Bros, Radium Engineering, Fragola, and DEI provide th...
