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 airflow
Smooth inner walls eliminate turbulence and restriction
Improves throttle response, turbo spool, and acceleration
Multi-layer high-temp silicone construction
Embedded stainless steel support wire prevents hose collapse
Ideal for stock or high-boost turbo setups
Direct-fit replacement for OEM turbo inlet hose
