Koyo Radiator for Skyline BNR32 RB26DET 89-94 - KL* 53mm Core Thickness (US = R)

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.

Koyo's "R" Series aluminum radiators feature a 53mm (2 1/16 in) thick, all aluminum core brazed to polished aluminum end tanks for a show quality finish. Koyo uses state of the art Nocolok Brazing Furnace to bond all of the radiator brackets, headers, tubes, and fins, creating high quality "indestructible" radiator. All aluminum end tanks are hand crafted using the latest Heliarc Soldering technique for the most reliable connections, then polished to a mirror finish
All Koyo Racing series radiators have "OE Specification" mounting location for stock mounting without major modifications; however we recommend using aftermarket electric fans for the best results. Koyo Hyper Radiator Caps are also available to increase your cooling system pressure to 1.3 bar for increased cooling capacity. Racing series radiators were made for manual transmission only, however with a separate automatic transmission cooler; one can use the Koyo Racing Radiator with automatics for increased cooling capacity.
