Here, you are looking at the CSF Racing 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. The pressure can cause a  leak which can lead to overheating and 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.
