Perrin Turbo Inlet Hose 3" Black | 2002–2007 WRX / 2004–2021 STI / 2004–2008 FXT | PSP-INT-410BK

Perrin's PSP-INT-410BK 3" turbo inlet hose replaces the restrictive, corrugated OEM rubber inlet on the Subaru WRX, STI, and Forester XT with a 5-ply wire mesh reinforced silicone unit. The smooth, non-corrugated interior maximizes airflow into the turbo — ideal for upgraded turbos where every CFM counts.

Key Features

• 5-ply silicone construction with wire mesh reinforcement — resists collapsing under boost
• Smooth non-corrugated interior for optimal airflow vs. OEM rubber
• Extreme heat soak resistance compared to factory rubber
• 3" diameter — designed for larger-than-stock turbos
• Maximizes intake tract diameter for increased power potential

Important Notes

• The 3" inlet will NOT fit the factory turbo — for upgraded turbos only
• New design includes wire mesh reinforced silicone to resist collapsing
• May require removal of intake manifold for installation

Vehicle Fitment

• 2002–2007 Subaru WRX
