Perrin Turbo Inlet Hose Red 08-14 WRX / 05-09 LGT / 05-09 Outback XT / 09-13 Forester XT | Increased Airflow | Performance Turbo Inlet Hose
Overview
The Perrin Turbo Inlet Hose is a direct replacement for the restrictive OEM turbo inlet hose found on select Subaru models including the 2008-2014 WRX, 2005-2009 Legacy GT, 2005-2009 Outback XT, and 2009-2013 Forester XT. Designed to improve airflow into the turbocharger, this high-quality silicone hose enhances horsepower, reduces turbo lag, and sharpens throttle response without requiring ECU tuning. It’s an ideal upgrade for Subaru enthusiasts looking to maximize their engine’s efficiency and performance while adding a clean, vibrant red accent to the engine bay.
Engineered with a smooth internal bore and a larger diameter than the OEM part, the Perrin inlet hose eliminates the pleated design that restricts airflow. The hose is reinforced with a stainless steel support wire embedded within the silicone layers, providing superior durability and preventing collapse under high boost or when paired with restrictive air filters. Additionally, the inclusion of a glass-filled nylon coupler and machined aluminum blow-off valve connection ensures a rigid, reliable fit that stands up to the heat and demands of spirited driving or track use.
For Subaru owners, this turbo inlet hose offers tangible performance gains by improving turbo spool time and overall engine responsiveness. The plug-and-play crankcase vent connector preserves emissions compliance without modifications, making it a practical upgrade for daily drivers and performance builds alike. Whether you’re looking to enhance your WRX’s power delivery or improve the throttle feel on your Forester XT, this inlet hose is a proven, platform-specific solution that complements Subaru’s turbocharged engines.
