Less parasitic drag on engine. Fan will only run when needed only causing drag from alternator, but not as bad as fan clutch. Less wear on water pump bearings, not spinning fan which can cause vibration on bearings. Quicker warmup for better gas mileage and emissions.
Cost is up to you. You can get a tauras fan cheap at a junk yard and wire it direct. Or spend a little more money and get a thermostatic switch to control when fan comes on. Or spend a little more and get a variable speed controller which turns fan on at lower speeds as engine reaches programmed temps, usually 60-100% depending on settings. It provides for less shock on electrical system. Or you can spend a whole lot more and get a e fan kit (whick includes fan, relay, ac relay, thermostatic switch, and vsc) from Summit Racing or Jegs.
