The Mishimoto Subaru radiator features all-aluminium construction, which provides increased heat and pressure tolerance, improved heat dissipation, and improved cooling efficiency. The 100% brazed aluminium core and TIG-welded end tanks provide optimal durability and years of efficient and reliable service. This radiator is a complete bolt-in unit that replaces the factory radiator without requiring any modification to your Subaru. The Mishimoto Subaru Performance Aluminium Radiator includes a high-pressure 1.3 bar radiator cap. This cap effectively raises the boiling point of the coolant, thus providing a higher threshold for safe temperatures and resulting in a more efficient cooling system. Additionally, a second radiator cap is included for use on the expansion tank. This radiator provides a significant increase in coolant capacity, which allows for aggressive driving while retaining safe coolant temperatures. Keep your Subaru on the street and out of the shop with the Mishimoto Subaru WRX and STI Performance Aluminium Radiator. As with all our products, this radiator includes the Mishimoto Lifetime Warranty.
