What's the whole point of changing the oil cap? I've seen a few of them here in the forum with users changing them. I'm not sure if this is supposed to improve performance slightly or is it just for aesthetic purposes?

it's jsut for bling factor... unless you're switching to something like the GrimmSpeed Air-Oil Separator which is used as a replacement to your cap.
