Ok so I was at the dealership today getting the dart detailed (they owed me one) and i asked about modifications and the warranty, as I just bought the car a little over a week ago and I have an extended warranty. Anyways, they told me that if you put on an aftermarket part it only voids the warranty for that part, For Example, if you put in an aftermarket suspension, the warranty is void for the suspension, if you put on an intake, the warranty is void for the intake etc...
Just thought I would share as these are all "new" cars and I know I was not the only one concerned about modifications and the factory/dealership warranty.
