Big believer in Derale fans. US made, they move a lot of air, and they last.
Sales guy at Motorstate( Lane Automotive) went to a seminar at Derale few years back. When I went in looking for a good fan to replace the fan that came in my current car when I bought it, he was emphatic not to use anything else they stocked except Derale. They had Spal and many other brands to choose from..
Installed it, night and day difference, couldn’t be happier.
