Boost performance and throttle response — the PERRIN Turbo Inlet Hose is a simple upgrade with big gains.Unlike the restrictive, pleated OEM inlet, the PERRIN Turbo Inlet Hose features a perfectly smooth interior and a significantly larger internal diameter — increasing airflow, reducing turbo spool time, and improving overall engine response. Whether you’re running a stock turbo or a high-output setup, this upgrade ensures your engine gets the air it needs, when it needs it.Built from multi-layer silicone and reinforced with an internal stainless steel wire, this inlet hose maintains its shape even under extreme boost or with high-restriction filters. That means consistent performance, long-term durability, and no risk of collapse under pressure.Larger internal diameter for increased airflowSmooth inner walls eliminate turbulence and restrictionImproves throttle response, turbo spool, and accelerationMulti-layer high-temp silicone constructionEmbedded stainless steel support wire prevents hose collapseIdeal for stock or high-boost turbo setupsDirect-fit replacement for OEM turbo inlet hoseWhat’s in the Box:PERRIN Silicone Turbo Inlet HoseStainless Steel ClampsInstallation InstructionsWarranty InformationFitment:Designed for Subaru WRX/STI models (verify compatibility with your year and trim before ordering)Installation:Difficulty: ★★★☆☆Time: 60–90 minTools Required: Basic hand tools, hose clamp driver recommendedInstructions: [View Here]Warranty:PERRIN Limited Warranty⚠️ PROPOSITION 65 WARNING:Cancer and Reproductive Harm — www.P65Warnings.ca.gov
