Features & Product Details

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

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, 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.

Q: Shroud SalLV5 years ago
Any idea if the Mishi fan shroud will fit on this or is it even necessary to install a new fan shroud? I was going to get the mishi one and figured I could also get the new fan shroud since it all fits better than the stock one but I didn't see anything about there being a problem with fan shroud fitment with this one (CSF).

  A: We cannot confirm fitment with the Mishimoto fan shroud to this radiator but it should fit with out any issues.
