I wonder what that part is to be used for?

My neighbor had his Harley Davidson engine fins done that way. Looked great

Greater surface area for more effective cooling, but requires more air flow because the wavy fins impede the passage of cooling air. Is it really worth the effort for the sake of appearance?
