Perrin 3in Turbo Inlet (PSP-INT-410BK) | Subaru WRX 2002-2007 / STI 2004-2021 / Forester XT 2004-2008

• Multi-layer silicone construction resists collapse under high boost
• Smoother, straighter airflow path improves turbo spool
• Compatible with most aftermarket intakes and big-turbo setups
• Replaces the OEM inlet for better reliability and flow capacity
