Description This 53mm R-Series Single Pass Radiator has been designed to fir the Series 4 RX-7 FC3s, build from October 1985 – Jan 1989, typically referred to as 86-88 model years. Double Pass/ N-Flo Technology – Strategically placed partitions make for and “N” or “U” shaped flow through the radiator core. This allows for improved cooling efficiency compared to normal all-aluminum racing models. Ideally suited for forced-induction applications. Construction is held to tight quality control standards that are illustrated in the outstanding Heliarc soldering, pristine tube and fin alignment, and mirror-like surface finish. The tubes, fins, headers, and brackets are brazed in a state-of-the-art Nocolok furnace, which bonds these components into a virtually indestructible radiator unit. All fan mounts are situated to OE specifications, and using the OEM mounting locations facilitates fitment into the FD3s. Why not include a set of SFS Performance Radiator hoses with your new cooling upgrade
