Do modifications void the warranty?
I encourage you to look up the Magnuson-Moss Act. Usually, only failures that happen, or repairs that are required that are a result of a modification can be denied, such as a differential failure or transmission failure being denied warranty coverage because you installed a modification that increased engine power.
