"Aftermarket" is a term used to describe parts that are not made by the factory. So for example, for your Hummer H1, if you buy parts for your car that are not actually made by Hummer, then those are termed "aftermarket". Many people use the term "H1 aftermarket parts" specifically when referring to custom parts for the H1, like performance parts or custom appearance parts. But even if you just replace your H1 brake pads with OEM-grade factory-style brake pads that are not made by Hummer, those too are aftermarket H1 parts. Over the course of a vehicle's life, it almost certainly will have aftermarket parts installed in it at some point, even if the vehicle is never actually "modded out".
