MAGNUSON MOSS WARRANTY ACT
US Code - Title 15, Chapter 50, Sections 2301-2312
According to the Magnuson Moss Warranty Act, a vehicle manufacturer cannot void the warranty of your vehicle due to an aftermarket part unless they can prove that the aftermarket part was the cause or contributed to the failure of the vehicle (15 U.S.C. 2302(C)). It’s always best to work with a performance-oriented dealership, but no matter who you choose, you’re protected by the law.
