QUick question, Does all these upgrades void the warranty?
I'll happily let others correct me if I'm wrong, but I believe the answer depends upon how and to what the warranty is being applied. To take an obvious example, installation of a COBB V3 would, I believe, have no effect at all on warranty if one's warranty claim concerns, say, seatbelts not fastening properly. However, if the warranty claim has to do with engine performance or drivetrain wear or some such that could be affected by the mod, then yes, the warranty may be void, at least with regard to that aspect of the vehicle and its performance. One (probable) upcoming exception to this might be the mountune MP 215 package, which when installed by a Ford dealer in the UK on a UK vehicle does not void the warranty, and word is that when this package hits the states, Ford will maintain full warranty on the vehicle when this is installed, as long as installation is done by a certified Ford dealer.
That all said, I'm willing to learn from others how many ways I got things wrong here.
