just put my RC dual fan in a week ago , drops my temps real fast , with a 160 therm temps falls from 170-140 real fast , was seeing 200+ before at idle 180 driving now its 170 or less never seen it above even with the AC running
price is great and shipping was very reasonable as well
its not an out of the box drop in but it fits great once you do the small mod
you have to cut the ears off the sides and make the groove where the ears were (to match the rest of the fan housing) and it just pops in between the radiator end tanks
to secure it in I pushed my fan to the bottom where it gets locked into the radiator shroud lower flange and used the factory fans lower metal bracket and moved it to the top(no screws in fan). Ive seen others use those plastic pin ties thru the radiator
The harness they sell will allow plugging right in to the factory harness , i didnt trust the factory wiring to run two fans so i went with the racetronix hotwire kit
If you feel you want to get the hotwire contact racetronix (advertisers marketplace thread) and put your name on the list , maybe he will make another batch . With his harness you dont need the ramchargers adapter but you do need to change the fan connector on the fan ( need to crimp and solder on three terminals and put them in the supplied plug end ) then its a plug and play . in an emergency you can now plug your factory harness directly into the fan if the relay on the hotwire harness ever fails
