Unique three-pass design maximizes cooling. CSF builds an industry leading, high-quality, all aluminum drop-in radiator that exceeds OE standards, gets rid of the plastic end tanks, and improves cooling by 25-30%.
All Aluminum tanks with High Efficiency "Triple Pass" Brazed Core design. Inlet/Outlet pipes are OEM "Quick Connect" type.
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.
