The Magnuson Moss Warranty Act (US Code-Title 15, Chapter 50, Sections 2301-2312) states that the manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to failure in the vehicle. We recommend working with performance oriented dealerships and shops, such as Arrington Engines. For additional peace of mind, Magnuson Products offers a limited extended 3-year/ 36,000-mile warranty for $200 that helps with potential problems with the dealership.
