Torque Solution 02-07 Subaru WRX / 04-21 Subaru STI HD Cast Aluminum 3in Hard Turbo Inlet
This hard turbo inlet replaces the factory plastic pipe on 2002-2007 Subaru WRX and 2004-2021 STI models. The 3-inch cast aluminum design increases airflow to the turbocharger for quicker spool-up and improved throttle response. It provides a direct bolt-on upgrade that withstands boost pressures and heat better than stock components.
Key Features
- HD Cast Aluminum Construction: Built from durable high-density aluminum to handle extreme heat and pressure without cracking or deforming
- 3-Inch Diameter: Larger size reduces restrictions and delivers more air volume to the turbo for enhanced power gains
- Direct Bolt-On Fit: Matches factory mounting points on WRX and STI turbo housings with no modifications required
- Improved Turbo Performance: Smoother interior flow promotes faster spool times and crisper throttle feel across the RPM range
- Precision Engineered: Designed and tested for Subaru EJ and FA turbo applications to ensure reliable operation
Product Notes
- Direct replacement for OEM plastic inlet pipe with included O-ring seals for leak-free installation
- Compatible with stock intercooler piping and most aftermarket turbo setups
- Carefully packaged to prevent damage during transit
Installation Notes
- Professional installation recommended.
- Remove stock plastic inlet by loosening compressor housing clamps and intercooler hose clamp
- Uses factory hardware and gasket. Torque clamps to Subaru specifications for secure fit

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...
