Koyo Aluminum N-Flow Dual Pass Racing Radiator - 93-95 Mazda RX7 (FD3S)

Koyorad 48mm N-FLOW Aluminum Racing Radiator 93-95 RX7 (FD3S) Koyo's "R" Series aluminum radiators feature a 48mm 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. Over 60 applications are available for Koyo "Racing" series. 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.
