A copy from the "Radiator Airflow Question" Post.
One little thing I've noticed about the front license plate is that it can be moved up about half an inch. Since the front spoiler is not anything like aluminum or metal, I easily drilled in two holes parallel to the stock holes. Just put the plate back on w/ the screws, but I wouldn't want to tighten the screws all the way, because you'll need the tread to keep the screws to stay in place. I just thought a little more airflow will keep the fluids a little more cool, but if you want the antifreeze to stay cool longer... add some Redline Wetter Fluid or similar. I don't know if this little mod will help, but it will keep more air flowing through the radiator without having the front plate taken off. A little 10 min mod with a drill...
