Mr.Goodwrench usually doesn't care depending on who your dealer is. Some dealers don't care at all and even if your car is highly modded and runs 11'* they will still replace trannies and stuff, and some refuse to work on the car. Unless the problem you have is with the air intake there shouldn't be any problems. Like for instance, if your seat heater quits, it doesn't have anything to do with the gutted airbox, so they have to fix it. We had to bring the GTP into the dealer for a problem we thought we had, but before they started working on it we figured out that the problem was simply a vacuum line that was disconnected luckily, but they had no problem with the mods that we had because the problem had to do with the fuel pump (we thought), and they know the mods didn't cause that, so they were going to work on it under warranty. Now if the tranny went, it would be another story.
