My dealer claims Autolite® plugs voids the warranty. Is this true?
A. If your local dealer is making a vehicle warranty contingent upon the use of their products, there may be a violation of Federal Law. As stated in the current Autolite® catalog as part of the Magnuson-Moss Warranty Improvement Act, “Using Autolite® or other quality brand name spark plugs does not void vehicle warranty”. Magnuson Moss warranty information is also available in the document titled “It’s the Law”.
