2022-2026 Subaru WRX

Upgrade airflow and throttle response with the PERRIN Turbo Inlet Hose, engineered specifically for the 2022+ Subaru WRX. This performance-focused inlet replaces the restrictive factory hose, improving airflow efficiency between the intake system and turbocharger for quicker spool-up and more responsive power delivery.

Constructed from high-strength, heat-resistant materials, the PERRIN Turbo Inlet Hose is designed to withstand elevated boost pressures and under-hood temperatures without cracking, collapsing, or swelling like OEM rubber components. Its smooth, optimized internal profile reduces turbulence, helping maximize airflow consistency and turbo efficiency—especially when paired with additional performance upgrades.

Designed as a direct-fit upgrade, this inlet hose installs using factory mounting points and delivers noticeable improvements in throttle response and drivability for both daily driving and spirited performance use.
