Thanks for the replies and I probably will leave it as is. No there is no overheating or anything, just a thought for cosmetics while I had the hood up looking at my engine compartment. I had a picture of some shiny blades in my head that would complement my stainless steel braided hoses,etc.
The euros were a snap to install and I used the wipers existing mount hole for one side and to secure the other side (although it isn't absolutely needed to do this) I made a bracket you can find at any hardware store.Again, that was a cinch too.
I agree about the star...I'll just replace with a new chrome one because mine is dull as you can see.
