Flex-a-lite high performance flex fans are designed to give you maximum airflow at low RPM, and the least amount of engine loading at high RPM. Less resistance at highway speeds equals more horsepower and better gas mileage. Flex fans pull additional air through the radiator at low RPM when the speed of the vehicle isn't 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. Will require additional spacer kit ( PT #1093027 ) for complete installation.
*NOISE DISCLAIMER: By design, Flex Fans are noisier compared to a stock fan. Noise WILL NOT be a valid reason for the return of this item.
