Fortunately, that link only gives you about 1/2 of the law; the The Magnuson-Moss Warranty Act.
Of course, since that site supports aftermarket part suppliers, it focuses just on the part of the law which favors them, and pretends the rest of the law doesn't exist. IMHO, that is pretty irresponsible.
There is another part of the same law, which favors manufacturers. It allows them to completely, 100%, void the warranty if there is
any sign of abuse. Not just the warranty directly associated with the part, but the entire warranty. What's is a sign of abuse? For our discussion here, such a sign can be the installation of any
high performance part. The theory is, if you install high performance parts, you must be making use them. Of course, if it went to trail, you could try to convince a judge that you have never done such (made any use of the high performance parts you installed), but good luck.
Of course, all of this depends on your dealer and their service department. They can simply overlook any mods you made, and not affect your warranty at all. Or, they can note your mods into the manufacturer's database, and have your warranty voided. So, it always pays to be real nice to whomever to talk with, at the dealer.
