the use of these fans provides little gain. many that believe these do work good is because the fan clutch that they dropped for this flex fan was worn out.
just remember the fan diameter must be the exact same as the fan OEM in there..
the clutch fan when hot out engages more its variable. so lets say you have AC its very hot out the flex fan may cause you to loose your cool....
when your at hywy speeds the clutch cools then the fan is not engaged but free wheeling so flex fan you may loose MPG at higher speeds since it is always engaged .
