Overview
The Perrin Turbo Inlet Hose is a direct upgrade designed to improve airflow to your Subaru’s turbocharger, resulting in increased horsepower, reduced turbo lag, and enhanced throttle response. This high-quality silicone hose replaces the restrictive OEM inlet hose, offering a smoother internal surface and a larger diameter to maximize air intake efficiency. It’s an ideal choice for Subaru WRX, Legacy GT, Outback XT, and Forester XT owners looking to unlock additional performance without complicated modifications.
Engineered with durability and performance in mind, the Perrin inlet hose features a stainless steel support wire embedded within the silicone layers to prevent collapse under high boost pressures. The smooth nylon coupler ensures a seamless transition from the intake to the turbo inlet, while the integrated blow-off valve connection simplifies installation and maintains a secure fit.

By eliminating the pleats and restrictions found in the OEM hose, this inlet hose improves turbo spool time and overall engine responsiveness. The plug-and-play crankcase vent connector preserves emissions compliance without the need to defeat factory systems. While no ECU tuning is required to enjoy immediate power gains, additional tuning can further optimize performance. This upgrade enhances the driving experience for Subaru owners seeking a practical and durable way to boost their vehicle’s turbo efficiency.
