the only two electric fan companies that I found to actually make claimed air flow are Spal and Tri-Pac.

when they say it moves 2500 CFM with a 1.4" restriction core, it actually does.

Spal and Tri-Pac are the choice for most OEM off-road manufacturers when it comes to electric fans.

any fan will work on a vehicle that does not tow. also, a fan is not needed if you drive faster than 25mph, because above that speed, ram-air is moving more air thru the radiator than any fan would be able to. If you tow, an engine driven fan is recommended.

The problems we face today can not be addressed at the same level of intelligence we were at when we created them - Albert Einstein Or with the same level of $ - Me
