The Aluminum Racing radiator will greatly improve the cooling efficiency on the Subaru BRZ.

This is the Koyo Aluminum Racing Radiator. This radiator features all-aluminum construction to not only improve the cooling efficiency of your vehicle but it will also be much more durable when compared to your factory radiator. Depending on your application, most factory-issued radiators will have plastic upper and lower tanks. These tanks will expand under endless heat cycles, and eventually, they will give out and can cause a leak. If you do not replace the radiator asap, this can cause overheating issues which can cause major engine damage. The Koyo unit may just be the last radiator that you would've to purchase because of the all-aluminum construction that can be welded and repaired in the future if you should happen to run into any leaking issues due to damage.
