PERRIN 02-25 Subaru WRX / 04-21 STI / 13-26 BRZ/GR86/FRS/86 Coolant Overflow Tank - Red

If you're looking to clean up the engine bay on your 2002-2025 Subaru WRX, 2004-2021 STI, or 2013-2026 BRZ/GR86/FRS/86, replacing the factory plastic coolant overflow tank with a PERRIN unit is a great way to do it. This tank serves the same purpose as the original, catching excess coolant that expands when the engine gets hot and returning it when it cools down, but it does so with a much cleaner look.

This overflow tank is CNC-machined from aluminum for a solid build that resists cracking and discoloration that can happen with plastic over time. The red finish gives your engine bay a pop of color and a more finished appearance than the stock tank. It's designed to fit right in place of the original, making the swap straightforward.
