The Mishimoto WRX and STI performance aluminum radiator is designed to maximize cooling efficiency by up to 30%, boost engine functions, and most importantly protect your car from overheating. The Mishimoto aluminum radiator features a lightweight dual core, 100% brazed aluminum, and polished end tanks, enhancing the overall performance of your engine. Every Mishimoto aluminum radiator is a direct OEM fit making installation effortless with no cutting or modification required. All Mishimoto radiators come with a high pressure 1.3 bar Mishimoto radiator cap and a limited lifetime warranty including accident protection. Mishimoto makes excellent radiators for both the daily driver or dedicated track car.

If you need even better cooling, Mishimoto's X-Line racing radiator has 3 rows for a core that is 25% larger than the standard version. The triple core design of the X-Line radiator allows more coolant to flow through the core for maximum cooling capacity. Each application is designed as a direct OEM replacement, with no customization required for installation.
