Even better cooling than the 7504 bolt in design, our 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 our fin design is so efficient we can reduce engine temperature substantially. This radiator requires an installation kit and a hose kit to install. 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 24inch x 2 1/4inch thick core and 19 x 28 overall.

Electrolysis Warning - We have had reports of certain electrolysis abnormalities with some vehicles, especially 2nd generation RX-7's which can quickly eat through and destroy aluminum radiators. An electrolysis test should be performed before installing ours, or any aluminum radiator to detect and repair any such situations. These problems are a result of something wrong with your vehicle, allowing abnormal currents into the coolant system. AWR will not warrant against such situations. AWR will be posting information soon on how to check your vehicle.
