Hi. I know modifying anything under the hood will avoid your factory warranty.. I like to know what this exactly means? let's say you threw in some aftermarket intake and computer chip.. Now,, if anything happens to those two, I am not covered right? Or is it that M-Benz will charge you for everything that they for your car.. once you modify anything under the hood??? I am not very clear about what's affected and what's not.. Please help me out on this one.. Thanks.
