I had some overheat problems with the stock hood heat shield, and air intake on my GT4. I cut a hole in the heat shield, its now completely open and installed an air intake and it made a mpg difference for me. Reason being that the old intake setup was sucking in hot air and making everything work harder, and not to mention it would get so hot that stuff would melt.

Yaris shouldn't be doing that though....
