  • 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+ STI / WRX coolant overflow tank is constructed from durable, TIG-welded aluminum for optimal durability and longevity.

  • The PERRIN coolant tank adds clearance for aftermarket intercooler piping and is a great compliment to competitive kits that don’t include one. The universal design will work with nearly all coolant systems that have OEM over flow tanks.

  • This product was designed to create more space in the engine compartment. Combining two reservoirs into a single component frees up space for intercooler tube placement, easier maintenance, access to the engine, and durability.

    • The OEM plastic reservoirs are replaced with CNC laser cut and formed aluminum that hand TIG welded to provide reliability under the most severe conditions.
    • CNC machined cap retainers assure these caps will never pop off.
    • All fittings and hoses are DOT approved, meaning they cost more but are actually designed to provide reliability under extreme temperatures and chemical exposure.
    • Designed to work with 2002+ WRX/STI models
