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 aluminum coolant expansion tank. The all-aluminum, 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 aluminum coolant expansion tank offers a 22% increase in fluid capacity over the factory expansion tank.

This direct-fit expansion tank upgrade is compatible with the stock Subaru and Mishimoto radiator caps, and is available either in polished silver, to match the Mishimoto Performance Radiator, or in Stealth Black. As with all our products, this expansion tank includes the Mishimoto Lifetime Warranty.
