I just put on a new intake on my duramax. It is a AEM Brute Force Air Intake. If something breaks on my truck should I put my stock air box on before taking it in for service or should they honor my warranty. I know this has been a debate for a while but what does GM have to say about this. I know on my old powerstroke I had it straight piped chiped and air intake on it and they always honered my warranty and said they liked the way it ran. I just wanted to know how GM treats people with mods done to their rigs.
