Under the act the manufacturer of the car would have to prove that the installed aftermarket part caused the failure of whatever you are claiming under warranty.

Here is a good example from autos.aol.com:

"You install an aftermarket air dam system to channel more air to the cold air intake system that you installed. The air dam system causes the vehicle to overheat because it restricts airflow over the radiator. As a result of overheating, the engine blows a head gasket and a cylinder head is warped. The car is still under warranty. You take it to your dealer and they determine that the aftermarket air dam system caused the overheating and thus the cylinder head damage and gasket failure. The carmaker is not obligated to perform any repairs under the provisions of the warranty."
