Koyo R-Core Radiators are the thickest Koyo radiators on the market. If your car has extreme cooling needs or you have a large front mount intercooler blocking your air flow the R-Core is the way to go. Although Koyo R-Core radiators are thicker then stock, they are bolt on and fit like OEM with little to no modification. The radiator is fully polished to a mirror finish and provides 20% to 30% more cooling than the standard OEM radiator. All Koyo aluminum radiators are made from aircraft quality aluminum with heli-arc welded cores that are NOCOLOK-brazed. They are built to handles high revving, high performance motors, and is perfect for turbocharged, supercharged, and nitrous oxide equipped engines. The OEM radiator cap will not fit, so depending on your application you might need to purchase Koyo radiator cap part # SKC-13.
