5-Ply Silicone Inlet Hose for GD WRX and Version 7-9 STI

Tomioka Racing's silicone turbo inlet hose for the 2002-2007 Subaru WRX and 2004-2007 STI uses 5-ply silicone with a larger bore than the factory hose and no pleated accordion section. The smooth bore design improves airflow to the TD04/VF-series turbochargers on these applications. Wire reinforcement ensures the hose does not collapse under the negative pressure generated at the compressor inlet.

Available With BOV Port Options

Available with machined aluminum BOV inlet port for installations running an aftermarket blow-off valve. Bolt-on installation with supplied clamps. A direct improvement over the factory hose for modified GD-era Subaru builds.
