Hood Scoops?

[circmand]

Searching VX's for sale I ran across a couple with hood scoops. I was wondering what's up with that.

Was it a factory option?
Are they cosmetic or actual air intakes?

I found that the hood insert is removable and that the metal underneath it is solid, so an actual air intake would seem to require cutting the hood.

Some are plastic glued on some are operational but done by an owner probably without any real investigation on whether it improves performance
