Koyorad: Alloy Radiator (Dual pass): Mazda Savanna / RX-7 Man. 01/89-10/91 (Dual pass)
N-FLO Technology
This is Koyorad’s N-Flo Technology which allows for a double pass radiator. This design cools more efficiently by allowing the coolant to remain in the radiator for a longer period of time therefore transferring more heat to the surrounding air. N-Flo Technology is for cars that are known to have limited airflow to the radiator.
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.
