Mishimoto X-Line Radiator 2002-2007 WRX/STI

The Mishimoto X-Line performance aluminum radiator for the Subaru WRX and STI is designed with a larger 3 row core to maximize cooling efficiency, boost engine functions, and protect your car from overheating. It is the ideal upgrade from the stock Subaru radiator whether you drive your vehicle daily or take it for track runs. The Mishimoto X-Line aluminum radiator features a lightweight triple core, 100% brazed aluminum, and polished end tanks enhancing the overall performance of your engine.

All Mishimoto radiators come with a high pressure 1.3 bar Mishimoto radiator cap and a great warranty including accident protection. Check out the Subaru WRX and STI Hose Kit for even more cooling efficiency.

Note: This radiator is intended for manual transmission vehicles only. If you have an automatic transmission, you MUST use an auxiliary trans cooler to use this radiator.  

Also note that this radiator is much THICKER than the stock one! You WILL have to adjust and/or customize to fit this radiator. Be prepared to trim radiator hoses (especially the upper hose), and/or relocate or replace the coolant overflow tank as necessary to make room for this radiator. If you are not comfortable with modifying the engine bay setup in this way, we suggest the standard Mishimoto 2-row radiator. We will not accept returns because you couldn't figure out how to mount this oversized radiator in your engine bay.
