I did not pull up any search results so figure I will ask. Has anyone had any engine components ceramic coated as a way of helping with heat reduction in the engine bay? I was thinking about doing a few things to help reduce heat as my engine bay get extremely hot. I've found some info online where people have done it and said it was good but also found info of the opposite. Any thoughts or suggestions? Also, what about teflon coating internal components as teflon has one of the lowest ( if not the lowest drag coefficients) and is enert to most chemicals.
