Flex a lite fans?

[Thighman]

Just curious if their 1300 fans are any better than stock. Also looking at their smaller 1000 series. I need to replace my fan and just wondering a good way to go and what spacer is needed.

Thanks

Thats the fan I installed on my truck.
It takes about 10 seconds of being on to drop it a couple letters on the
thermometer (that says NORMAL)
