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
