Perrin Turbo Inlet Hose Black 2015-2021 WRX / 2014-2018 Forester XT | 3.0" Diameter | High-Flow Turbo Inlet Hose
Overview
The Perrin Turbo Inlet Hose is a direct replacement for the restrictive and often failure-prone factory turbo inlet hose found on 2015-2021 Subaru WRX and 2014-2018 Forester XT models. This upgrade is designed to improve airflow into the turbocharger, enhancing throttle response and overall engine performance for Subaru enthusiasts seeking a reliable and effective power enhancement. Whether you’re running stock or supporting modifications, this inlet hose helps unlock your turbo’s full potential.
Engineered with a multi-layered, fiber-reinforced silicone construction, the Perrin Turbo Inlet Hose offers superior durability and heat resistance compared to the OEM rubber hose. Its smooth internal surface and increased 3.0" diameter reduce airflow turbulence and pressure drop, allowing the turbo to spool more quickly and efficiently. The embedded stainless steel wire reinforcement prevents hose collapse under high boost conditions, ensuring consistent performance even in demanding driving scenarios.
For Subaru owners, this hose represents a practical upgrade that balances OEM-level fitment with performance gains. The improved airflow translates to sharper throttle response and potential horsepower increases when paired with supporting modifications. Its compatibility with popular aftermarket cold air intakes like Perrin, AEM, K&N, and Mishimoto makes it a versatile choice for WRX and Forester XT owners looking to enhance their turbo system without complex modifications.
