Product Description

The PERRIN PSP-INT-428BK Short Turbo Inlet Hose is engineered for the 2022-2026 Subaru WRX equipped with the FA24F 2.4L turbocharged boxer engine. Featuring a large 3-inch smooth-bore reinforced silicone construction, this inlet hose replaces the restrictive factory component to improve airflow into the turbocharger, resulting in faster spool-up, improved throttle response, and increased airflow capacity for modified vehicles.

Designed specifically for use with compatible aftermarket intake systems, the short inlet provides optimal fitment while maintaining excellent durability under elevated boost pressures and engine bay temperatures. The premium multi-ply silicone construction resists expansion and collapse, while the direct bolt-on design allows straightforward installation using the supplied clamps and factory mounting locations, making it an excellent upgrade for performance-focused WRX builds.
