Subaru WRX Coolant Overflow Tank - Perrin Performance - CNC-machined - Black - 02-25 replaces the stock plastic reservoir with a precision-crafted, CNC-machined Perrin coolant overflow tank. It’s a direct-fit upgrade intended for owners who want a durable, finished replacement for the OEM unit.

This Perrin overflow tank is machined to close tolerances and finished in black to match performance engine bays. It fits 2002–2025 WRX applications and is also compatible with many Subaru/Scion models in the same era. As a metal replacement for the OEM plastic tank, it offers a more rigid component that resists warping and adds a cleaner, more purposeful look under the hood without requiring modification to factory mounting points.

Features

• CNC-machined construction for consistent fit and finish
• Black finish for a low-profile, performance-oriented look
• Direct replacement for the OEM plastic coolant overflow tank
• Compatible with 02–25 Subaru WRX and applicable STI/BRZ/GR86/FRS/86 models
