Some CAD work today

Today I installed a factory air dam that my car was always lacking. It was my understanding that the dam provided proper cooling to the car even with no direct flow through the grill so I tested it. After installing the damn I covered up the entire front end of the car to test this on my way home from work and it worked! Engine temp never rose above the normal spot on the gauge. Since the engine was able to cool, when I got home I taped over the cardboard to "waterproof" it because some rain is expected over the next few days. Sorry that it is kinda hard to see the dam in the pic. Only time will tell if the grill block will net better MPG. Unfortunately, I don't have a MPGuino to test running MPG to see if it's sipping less while running down the road so just have to wait to fill the tank a couple times to see if there is any benefits.

Comments and criticisms please. Did I do good? lol
