it will fit the i4 but it doesn't sit right around the area where the v6 fog lights would be so you would have to cut it. There is an i4 one that fits the i4 bumper but i have never seen a replica for it. Take a search around and you'll see some pics on here of it. You can also find pics of modified v6 lips on i4's as well as lips that have just been stuck on without cutting.
