They will do what they are for, if you are running forced induction, all you are doing is buying engine bay bling, nothing wrong with that and that is coming from a good trusted source,unfortunately otherwise I would be buying them
I can't find any images, but i know that Humpy had some wrapping done with pearl white and it matched the rest of the car.
So if the mirror caps are wrapped in white it would be easy to put back to oem,if it looks no good😁
