There are the rubber plugs in the 05' hood. Why????
I know that the engine would get dirtier, but I tend to wipe it off once a month anyhow, so that is not an issue for me. I'm wondering if they are there because GM found that they reduced airflow through the radiator at higher speeds, thus making the engine run hotter. Anyone have any thoughts on this?
