Rid your 2008-2014 WRX or 2005-2009 Legacy GT engine bay of the eyesore that is the stock expansion tank, and replace it with the Mishimoto aluminium coolant expansion tank. The all-aluminium, fully welded construction of the Mishimoto expansion tank does more than dress up your engine bay. This tank also offers increased durability during repeated cold and hot transitions, and leak-free welded CNC barb fittings. In addition, the Mishimoto aluminium coolant expansion tank offers a 22% increase in fluid capacity over the factory expansion tank.
