Not necessarily. Air dams add frontal area, and they help up to a point, but too big will just add drag(Vs optimally sized. Too big may still reduce drag from stock.). You don't want to prevent ALL air from going under the car. Hard to tell from the angle of the picture, but it looks like you would have maybe an inch and a half of ground clearance? That is not a whole lot. I have 4 inches of ground clearance in my accord thanks to its front wheel deflectors, and it scrapes more than my brother's LOWERED miata.

Try out the air dam as is, get a baseline for coasting/mpg. I would strongly recommend keeping both the top and bottom parts of the air dam as they are shaped for good mounting and good airflow respectively. If you want to shorten it, try cutting it in the middle and sliding it up, then bolting it together.
