The Mishimoto Performance Aluminum Radiator is a bolt-in cooling upgrade for the 2001-2007 Subaru WRX and STI (manual) and the 2005-2006 Saab 9-2X Aero, replacing the failure-prone plastic-tank factory radiator with no modification. It uses all-aluminum construction with a 100% brazed core and TIG-welded end tanks for improved heat dissipation, pressure tolerance and long-term durability. A high-pressure 1.3-bar radiator cap is included to raise the coolant boiling point.
