CSF High Performance Aluminum Radiator - Subaru Models (inc. 2008-2021 STI / 2015-2021 WRX / 2009-2013 Forester)

The 1-Row 31mm High-Performance Radiator will improve the cooling efficiency in the Subaru WRX/STI.

RallySport Direct proudly carries a great selection of quality racing radiators brought to you by CSF.

 

Here, you are looking at the new CSF 31mm 1-Row High-Performance Radiator. This is a super-durable all aluminum radiator designed to replace your factory radiator to improve the overall cooling efficiency. Most factory radiators are manufactured using plastic upper and bottom tanks which will eventually weaken over time, and will leak which will cause you to overheat, which will open up an entirely different set of problems. CSF relieves this issue with all-aluminum construction to essentially become the end-all-be-all of radiators.
