I’ve got this 18” version (they have smaller) on the front of my radiator purely to help cooling between runs at the track. It moves the air through the radiator quite well when I run it for that but it also blows a good bit from the sides on the front side of the radiator as expected. There are ways to help prevent that to some extent on a car, but not really on my setup. Anyway, the price has almost doubled since I bought mine about 2 years ago. :eek:
