Overview
The Perrin Throttle Body Hose is a direct replacement for the OEM rubber hose on select Subaru models, including the 2002-2007 WRX, 2004-2021 WRX STI, and 2004-2008 Forester XT. This high-quality silicone coupler enhances the intake system by providing a more reliable and leak-free connection between the throttle body and intake piping. Designed for both stock and modified setups, it improves throttle response and airflow consistency, critical for maintaining performance in forced induction Subaru engines.
Engineered with a 5-ply reinforced silicone construction, this hose resists heat, pressure, and oil exposure far better than the factory rubber counterpart.

The included clamps provide a secure seal, making installation straightforward and dependable.
For Subaru enthusiasts, upgrading to the Perrin Throttle Body Hose means reducing the risk of boost leaks and throttle response lag caused by aging or failing OEM hoses.
