Consider that while frontal area is great, there are two things you're going to run into.
1) The IC is going to start to go behind the bumper as we increase height, then the frontal area is not being increased.
2) Too bit = too much pressure drop. You'll have to compensate with more boost pre-IC to get the same boost post-IC. Like almost everything else in the automotive world, there is a happy medium.
Fortunately this bumper comes off with 2 bolts (okay the headlights too) but it's damned quick. Start with removing the grill and make some measurements. If I remember correctly there are people who have gone big enough with IC's to run into issues hitting the headlights (they removed AC components). So keep an eye out for that.
