Perrin 02-07 Subaru WRX / 04-11 STi Black Turbo Inlet Hose
Unlock smoother airflow and a crisper throttle response with the Perrin Turbo Inlet Hose. Designed to eliminate the turbulence and airflow restriction caused by the OEM plastic or rubber inlet, this high-performance upgrade is a must for any turbocharged Subaru enthusiast looking to improve power delivery and turbo efficiency.
Constructed from multi-layer silicone and reinforced with an internal stainless-steel support wire, the Perrin inlet hose maintains its shape under boost pressure and engine heat, unlike factory pieces that tend to collapse or degrade over time. The smooth internal bore eliminates accordion-style ridges found in stock inlets, allowing uninterrupted airflow to the turbo and minimizing pressure loss.
The design also improves the connection between your intake and turbo, creating a tighter, more secure seal that helps reduce the chances of leaks or vacuum inconsistencies. Expect quicker spool, improved turbo response, and a cleaner engine bay appearance — all in one.
Whether you're upgrading your intake system, chasing more boost, or just replacing a worn-out factory component, the Perrin Turbo Inlet Hose offers real performance gains backed by reliability and a precision-engineered fit.
