Mishimoto Performance Aluminum Radiator for 2002-2007 Subaru WRX/STI and Saab 9-2X Aero (MMRAD-WRX-01)

Fits 2002-2007 Subaru Impreza WRX/STI and 2005-2006 Saab 9-2X Aero.

The Mishimoto Performance Aluminum Radiator (MMRAD-WRX-01) is engineered to eliminate the primary failure point of the factory cooling system: the plastic end tanks. Over years of thermal cycling, OEM plastic becomes brittle and prone to cracking, which can lead to overheating and severe engine damage. This all-aluminum upgrade provides the heat and pressure tolerance required for both aggressive track use and reliable daily commuting.

Constructed from high-grade aluminum with a 100% brazed core and precision TIG-welded end tanks, this radiator significantly increases coolant capacity and improves heat dissipation. It is a direct bolt-in unit that installs without modifications. Each radiator includes a high-pressure 1.3 bar radiator cap to effectively raise the boiling point of your coolant, plus a secondary cap for the expansion tank.
