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

When you're working on your 2008-2014 Subaru Impreza, especially if you're rebuilding the cooling system or just want to clean up the engine bay, that stock plastic coolant overflow tank can be a real eyesore. Plus, those plastic tanks can become brittle over time from constant heat cycles and eventually crack, leading to coolant loss. This Mishimoto aluminum coolant overflow tank is a solid upgrade that addresses both issues.

This tank is TIG-welded from aluminum, making it much more durable than the original plastic one and resistant to cracking from temperature changes. It's designed to fit right in place of your factory tank, and it even comes with a CNC-machined dipstick so you can easily check your coolant level without having to guess. The polished finish looks sharp and will really make your engine bay stand out, especially when paired with other aluminum components or a Mishimoto radiator.

Installation is straightforward and usually takes less than 30 minutes. It's a practical way to improve the reliability and appearance of your Impreza's cooling system.
