Get that plastic blob of an overflow tank out of your engine bay. Stock plastic tanks are prone to failure due to repeated hot and cold cycles, and they create a horrible eyesore as they lurk in your engine bay. Mishimoto's 2008-2021 STI / WRX coolant overflow tank is constructed from durable, TIG-welded aluminum for optimal durability and longevity. Included with this STI / WRX coolant overflow tank is a CNC-machined dipstick to allow for easy checking of coolant levels. With the choice of two finishes, polished and anodized black, this tank will have no problem matching the style of your engine bay. This STI / WRX coolant overflow tank fits perfectly with the stock or Mishimoto's STI / WRX radiators. As with all Mishimoto's STI and WRX parts, this overflow tank includes the Mishimoto Lifetime Warranty.
