The Mishimoto aluminum radiator for 2001–2007 Subaru WRX and STI is a bolt-in performance replacement engineered to address the stock radiator’s weak points and improve cooling for spirited street or competitive use. With full aluminum construction, TIG-welded end tanks and a 100% brazed core, it increases coolant capacity and heat dissipation while including high-pressure caps and Mishimoto’s lifetime warranty.
