Mishimoto Impreza WRX / STI Aluminium Coolant Expansion Tank

Add some additional reliability and engine bay styling with the Mishimoto Subaru WRX 2002–2007 / STI 2001–2018 aluminium coolant expansion tank. Stock coolant expansion tanks are prone to failure after years of constant temperature variations. The Mishimoto tank is constructed from durable, TIG-welded aluminium with barbed fittings for optimal durability and longevity. This expansion tank provides a 50% increase in capacity compared to the stock unit.
