Mishimoto MMRAD-STI-08 - 08-09 Subaru WRX/STi Manual Aluminum Radiator

Performance Aluminum Radiator, fits Subaru WRX 2008-2014/Subaru STI 2008-2021

Whether you’re carving through back roads in your WRX or pushing your STI to the limit on track day, maintaining optimal coolant temperatures is essential to protecting your EJ engine. The factory radiator’s plastic end tanks and limited cooling capacity can quickly become a weak link, especially under the high demands of spirited driving or hot summer commutes. A failure in the cooling system can lead to overheating, head gasket issues, and costly repairs that cut your driving adventures short. The Mishimoto Performance Aluminum Radiator for the 2008–2014 Subaru WRX and 2008–2021 Subaru STI is engineered to be the ultimate safeguard for your engine, delivering improved cooling efficiency and durability over stock. -- Built with a lightweight, dual-core design and 100% brazed aluminum construction, this radiator maximizes heat dissipation and withstands higher pressures to keep your engine performing at its best. The TIG-welded, polished end tanks add strength and a premium finish, while the direct-fit design ensures a straightforward installation with no cutting or modification required. The included high-pressure 1.3 bar radiator cap raises the boiling point of your coolant for an extra margin of safety under heavy loads, and a second radiator cap is included for use on the expansion tank. With up to a 30% increase in cooling efficiency over the factory unit, this upgrade is ideal for daily driving, spirited runs, or competitive use. -- Backed by the Mishimoto Lifetime Warranty, including accident protection, this radiator is built to keep your Subaru running strong for years to come.
