Mishimoto 01-07 Subaru WRX and STi Manual X-LINE (Thicker Core) Aluminum Radiator

If you're pushing your 2002-2007 Subaru Impreza WRX or STI hard, especially with a modified turbo setup, keeping engine temperatures in check is crucial for reliability. This Mishimoto X-Line radiator is built to handle the extra heat generated by aggressive driving and performance upgrades. Its full aluminum construction and substantial three-row core mean it can dissipate heat much more effectively than the stock unit.

This radiator features a 100% brazed aluminum core with TIG-welded end tanks, making it a well-built and durable part that can handle higher pressures and temperatures. The larger, three-row core design increases the surface area for better heat transfer, which directly translates to lower coolant temperatures. Mishimoto also includes a high-pressure 1.3 bar radiator cap to raise the coolant's boiling point, further enhancing the system's efficiency and safety. You'll also find a magnetic drain plug included, which helps catch any stray metal fragments circulating in your coolant, adding an extra layer of protection for your EJ engine.

This Mishimoto X-Line radiator is a solid option whether you're replacing an old radiator or looking for an upgrade that can keep up with track days. It's designed to fit your 2001-2007 WRX and STI, offering improved cooling performance and longevity.
