Koyo 08-15 Subaru WRX / STI 05-09 Subaru Legacy GT 2.5L (MT / w/ Filler Neck) Radiator

Koyo is a well-known name for making solid cooling system parts, and this radiator is a great example of their work. If you're looking to keep your Subaru running cool, especially if you've added some performance modifications or just want a more robust replacement for your stock unit, this Koyo radiator is a strong option. It's built to handle the demands of vehicles like the 2008-2014 Subaru Impreza, the 2015-2019 Subaru WRX, and the 2005-2012 Subaru Legacy, among others.

This radiator features an all-aluminum construction, which is lighter than stock and also helps with heat transfer. The core is designed for improved cooling efficiency, meaning it can dissipate heat more effectively than a standard radiator. This is important for preventing overheating, especially during spirited driving or in warmer climates. It's designed to fit with the factory filler neck, making installation more straightforward.

When installing a new radiator, it's always a good idea to flush your cooling system and use fresh coolant. This ensures you get the best performance from your new Koyo radiator and helps protect your engine. This radiator is a direct fit for a range of Subaru models, so you can be confident it will integrate well with your existing cooling system components.
