Product Description

The PERRIN PSP-ITR-201RD red aluminum charge pipe is engineered for the 2022-2025 AWD Subaru WRX with the FA24 turbo engine. It replaces the restrictive OEM plastic pipe with mandrel-bent smooth-bore aluminum (2.25" → 2.75") and a CNC-machined turbo flange, restoring airflow efficiency, sharpens boost response, and adds a striking engine-bay visual.

Installation is direct bolt-on using factory mounting points, with reinforced silicone couplers and secure T-bolt clamps. No ECU tuning required for stock or FMIC-equipped systems - the OEM o-ring interface ensures leak-free performance. Compatible with OEM, PERRIN top-mount, or front-mount intercoolers for 2022+ models.

Fitment spans 2022-2025 WRX (AWD, FA24 turbo). Additionally, this pipe is backward-compatible with 2015-2021 WRX/STI when used alongside the PERRIN FMIC kit (PSP-ITR-437-1). Fitment confirmed through 2025 by multiple authorized dealers. AWD only.
