These splitters install easily. They require no modifications to your stock fascia, and only attach in the wheel well. We have an ABS plastic piece on both sides that extends out to align the stock holes on the inner wheel well with the holes on the splitter. First time shouldn't take more than 30 minutes. Once you are used to it, you should be able to get it on and off in under 10, if not 5. These are part of the sale we have going on, so if anyone wants one, now is the time to order.
