Features & Product Details

CSF manufactures high-quality aluminum racing radiators for those of you looking for a great solution over your leaking or warped OEM unit. These are TIG welded from military-grade aluminum and are engineered to OEM specs. This means that it’s a direct drop-in solution that requires no further modifications, or alterations to make it fit. 

Also, their product testing includes thermal cycles, burst pressure testing, vibration testing, and even as far as wind-tunnel testing to provide the consumer with a product that can be trusted for street use, but good enough for track use. 

These radiators have also gone through a mirror-polishing process that will enhance the engine bay. So no more looking at plastic cores and end tanks. With all said, you will have a strong radiator designed and built to withstand all conditions, while improving your cooling.

  • Q: radiator cap  easton_palmer605242 years ago

    does it matter what cap i use? the stock sti 1.3 or the 1.4 that comes with this radiator? Ive been told that you should put the stock sti 1.3 on the new radiator.

      A:  You can use either cap for the radiator. It is recommended using the provided CSF cap for the overflow.

  • Q: Shroud  SalLV3 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.
