  • 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.

  • Premium radiator has 3-row core for improved strength and reliability.
  • 16% thinner-than-stock tubes allow for more surface contact, increasing cooling efficiency.
  • Greater density of rows for higher cooling capacity.
  • More contact points for additional heat transfer.
  • 3-row design creates more air turbulence, maximizing cooling efficiency.
  • Includes magnetic drain plug
  • Includes a high-pressure 1.3 bar Mishimoto radiator cap.
  • Lifetime warranty

  • Caution: The provided Mishimoto radiator cap should replace the stock cap located on the expansion tank. The stock cap attached to the radiator should be installed on the Mishimoto Performance Aluminum Radiator. The Mishimoto radiator cap is a two way valve, while the stock radiator cap is a single valve. Due to the difference in construction, the Mishimoto cap cannot be used on the radiator. If the Mishimoto cap is fit on the radiator, overheating may occur.It is the installer's responsibility to check all thermostat plugs, NPT plugs, line fittings, and other connections to assure they are fully tightened before operating the vehicle. Mishimoto recommends that you check all connections at regular intervals, especially during the first few miles after installation. For additional technical information, contact sales@mishimoto.com.

    Fits all 2002-2007 WRX and STI. Note that 2002 models have a slightly different overflow tank arrangement that may require some custom plumbing with this radiator.
