technically, at least on the mp3 even with piaa's, the stock fogs are useless anyhow. I've got mine aimed a bit higher, but they still don't make a big difference at night. Drive around with the headlights off, and just the fogs on and you can see that they actually make a some light on the road, but not much. Their more for looks then anything, but i find that the little light that they do make, you become used to it, and when their not on, you miss them. Sometimes it take me quite some time to realize that their not even on though.
Just a useless point I thought I'd mention
