Whether you’re logging miles on your daily commute or chasing lap times at the track, keeping your Subaru’s flat-four cool is key to reliability and performance. The factory radiator’s limited capacity can quickly become a bottleneck under demanding conditions, putting your engine at risk of overheating and costly damage. The Mishimoto X-Line Performance Aluminum Radiator for the 2008–2014 Subaru WRX and 2008–2021 Subaru STI is designed to be the ultimate solution, offering maximum cooling efficiency and durability for any driving environment. — Engineered with a larger triple-row core, this radiator delivers significantly improved heat dissipation to keep coolant temperatures in check, even under extreme loads. Its 100% brazed aluminum construction and TIG-welded polished end tanks provide superior strength and longevity compared to the stock unit, while the lightweight design helps maintain vehicle balance and performance. The direct OEM fit ensures an easy, no-modification installation, so you can spend less time in the garage and more time enjoying your Subaru. — Every Mishimoto X-Line Performance Radiator includes a high-pressure 1.3 bar radiator cap to raise the boiling point of your coolant, offering additional protection against overheating. Additionally, a second radiator cap is included for use on the expansion tank. Backed by the Mishimoto Lifetime Warranty with accident protection, this radiator is built to keep your WRX or STI running cool and strong for years to come.
