16" is plenty big for most auto applications. One 16" can easily cool a big V8. Plus a bigger fan is going to need a bigger motor and more electrical current as well. There aren't many 18" electric fans that I could find, and the ones that I did find didn't flow much air. What really matters is the CFM; how much air the fan can move. The speed of the motor and the shape of the fan blades is what matters.
