NO IT WILL NOT. Conditions that may void a vehicle's warranty are specified in a federal law called "the Moss-Magnusson Act" which stipulates that dealers cannot void a warranty because vehicles have aftermarket parts. If a dealer could prove that a particular aftermarket part caused a particular failure, then they could disallow the claim for that issue only. For example, if your engine were to fail, the dealer could not refuse to fix it because the vehicle has aftermarket wheels. However, if your engine had been modified, then, they may have a case and may try to deny the claim. We don't modify engines in any way.
