I have given consideration over the validity of my planning for modifications on my car. Moon Caps and Wheel Skirts will be my main focus. I am gathering from the data from other modders that that the combination of those two should give me an improvement of 1-1.5mpg.

I have concerns over the Grill Block. Most of the airflow appears to be at the lower portion of the Grill Block with one large section and two sections on the side. I have a very narrow upper Grill. My last car blew head gaskets because of overheating for other reasons and I am a bit weary on such matters. In the planning stages, do you use temporary measures such as cardboard and duct tape on partial sections to determine if the engine is sufficiently cooled without the need for the fan?
