Turbo Flex Flex Fans pull additional air through the radiator at low RPM when the speed of the vehicle is not enough to cool the engine's coolant system. At higher RPM, when the vehicle's speed forces ample air through the radiator, the fan blades flatten out, resulting in less power being used to spin the fan. Engine performance and gas mileage are thus improved.
Replaces stock fan clutch when maximum air flow is necessary for additional cooling. For use with stock fan blades. Gas mileage will drop because fan blades spin constantly for full-time cooling. NOT for use on high performance engines or engines that turn over 4200 RPM. Complete with mounting hardware and illustrated multilingual instructions.
