86-91 RX7 Crossflow Competition Radiator


AWR RX7 FC crossflow aluminum radiators

Even better cooling than above bolt in design, the new crossflow aluminum radiator retains the coolant in the radiator core longer. Coolant has to pass from side to side lengthwise instead of up and down in the radiator. Keeping the coolant in the radiator longer will generally dissipate [radiate] more heat out through the fins and since the fin design is so efficient, engine temperatures are reduced substantially. It will require slight modification on a street car. This is the ultimate set-up for running the 13B in full racing trim. Comes with installation kit. The standard radiator is sufficient for IT cars and hot street cars. 18 1/4' tall x 24" x 2 1/4" thick core and 19 x 28 overall.
