^^(Nismosigma) Exactly. If all else fails, I'd go with the lip. But I'm trying to find a cover that comes more forward than stock, and has a larger, more squared opening in the middle. The way I have the intercooler mounted behind the stock cover is cutting airflow by 25%. My intercooler core measures: 24x11x3. I really didn't want to hack the bumper itself, so I just mounted it under the bumper at a swept-back angle until I could come up with something else.
