Perrin 3.0” Turbo Inlet Hose | 2002–2007 Subaru WRX / 2004–2021 STI

Upgrading to a 3.0” turbo? Ensure your inlet can handle the flow.

The Perrin 3.0” Turbo Inlet Hose is engineered for high-performance Subaru builds utilizing larger turbochargers. Designed to replace the restrictive OEM inlet, this hose provides a smoother, more direct airflow path to the turbo, enhancing throttle response and reducing spool time.

Constructed from 5-layer reinforced silicone and embedded with a stainless steel wire, it maintains its shape under high boost pressures. The machined aluminum blow-off valve connection ensures a secure fit, while large ½” spigots accommodate increased airflow from crankcase vents and vacuum lines. 

This inlet hose is a direct fit for vehicles equipped with 3.0” turbo inlets, eliminating the need for custom fabrication.
