Mishimoto Performance Aluminum Radiator 2008-2014 WRX / 2008-2021 STI / 2009-2013 Forester XT / 2005-2009 Legacy GT / 2005-2009 Outback XT

Keep your EJ engine cool and protected, whether you’re carving back roads or pushing your STI to its limits on the track. The factory radiator’s plastic end tanks and limited cooling capacity can become a weak link under spirited driving or hot summer conditions, risking overheating, head gasket failure, and costly repairs. The Mishimoto Performance Aluminum Radiator is engineered to be a direct-fit, high-performance upgrade that improves cooling efficiency and durability over stock.
