Product Description

The Mishimoto MMRT-BRZ-13P Aluminum Overflow Tank is designed specifically for the 2013-2021 Subaru BRZ, 2013-2016 Scion FR-S and 2013-2021 Toyota 86 models equipped with the 2.0 L boxer engine. Constructed entirely from aluminum and finished in polished styling, this tank replaces the factory plastic unit with a premium upgrade built for durability and performance.

With its integrated sight tube you can easily monitor coolant levels under hot and cold conditions, and because it retains the factory mounting points and hose locations, installation is straightforward and modification-free. The upgraded material and construction help mitigate issues commonly found in stock tanks - such as cracking, swelling or discoloration - especially under performance driving or repeated thermal cycles.

Ideal for daily drivers, sports-car enthusiasts, or track-use builds, the MMRT-BRZ-13P brings both functional and aesthetic improvements. Before purchase, verify your vehicle's year and engine variant to ensure compatibility. While fitment covers up to 2021, coverage beyond that year is unconfirmed at the time of this listing.
