How do the plastic air foils that mount under the car, infront of the engine, help cooling? Are they worth adding?

Like Johny says above....
Actually they create a low pressure area behind them at speed and which helps draw down the air across they cylinders. Some of the race cars with big air dams actually remove the rear bumpers to help draw the cooling air out. |

(IMG:style_emoticons/default/agree.gif) That is the reason the 914-GT didn't have a rear valence. |
