Mishimoto 08+ Subaru WRX/STI Black Aluminum Coolant Overflow Tank

You're getting a black aluminum coolant overflow tank, complete with a CNC-machined dipstick for checking your coolant level. This part is designed to replace the factory plastic tank on your 2008-2014 Subaru Impreza WRX or STI. The stock plastic tanks can become brittle over time from constant heating and cooling cycles, sometimes leading to leaks or a less-than-ideal appearance in your engine bay.

This Mishimoto tank is built from durable, TIG-welded aluminum, which holds up much better to the temperature changes under the hood. The included dipstick makes it easy to check your cold coolant level, ensuring your system stays properly filled. It's designed to fit right in place with your stock radiator or even a Mishimoto radiator if you've upgraded that too. The anodized black finish gives your engine bay a cleaner, more finished look.

Installation is straightforward and typically takes under 30 minutes. This tank comes with Mishimoto's lifetime warranty, so you can be confident in its longevity.
