you will notice more power when switching to efans.
and you'll cool better if you have a good set of dual fans. i recommend getting a set of duals out of a junkyards of a maxima or altima, or similiar.
and don't bother with a fan temperature controller. just wire them to the ignition. temps are perfect on mine and i've been doing this for 4-5 months in all kinds of weather.
do it.
