Subaru BRZ Coolant Overflow Tank - Perrin Performance - CNC-machined - Black - `13-`25. This Perrin coolant overflow tank replaces the stock plastic reservoir with a precision CNC-machined aluminum unit finished in black for a cleaner, more durable engine-bay component.

Designed as a direct replacement for 2013–2025 Subaru BRZ models, this Perrin tank keeps the factory mounting points and function while offering improved resistance to heat and UV-related wear compared to the OEM plastic tank. The CNC machining delivers consistent fitment and a refined look without altering cooling system performance. It is intended for enthusiasts who want a long-lasting, well-made piece that complements other engine-bay upgrades.

Features

• CNC-machined billet aluminum construction for consistent fit and finish
• Durable black finish to resist corrosion and fading
• Direct-fit design that uses factory mounting points
• Maintains original coolant overflow function—no modification to cooling system required
