Ok. I'm going to type this as slow as I possibly can. Please read equally slow and, if you have any literate children, ask them to help you read what follows.
The Mag.-Moss Warranty is a consumer protection statute. It was enacted, in part, to protect consumers from having warranties voided when they install aftermarket parts. (1) Your OEM warranty only covers your vehicle exactly as it existed when it left the factory; (2) A manufacturer cannot wholesale void your warranty simply because you have added an aftermarket part, regardless of who made the part; (3) A manufacturer is not under any obligation to, and will not, warranty parts you put on the vehicle after it leaves the factory; (4) If a new non-OEM part causes damage to an OEM part, your warranty will be useless.
