Aftermarket parts are manufactured by a company other than your car manufacturer. They can be produced at a high volume and made to fit the specifications of different types of vehicles, not just a single car make and model. Aftermarket parts are usually less expensive than OEM parts; The aftermarket companies reverse-engineer the part.
OEM Parts refer to the parts are made directly by the car manufacturer, not by a third party. OEM parts, because they’re made by the manufacturer to fit the specifications of a particular make and model, tend to fit perfectly.
When referring to auto parts, OEM refers to the manufacturer of the original equipment, that is, the parts assembled and installed during the construction of a new vehicle.
Advantages
Easier to choose your part: If you go to the parts counter at a dealership and ask for any part, you’ll usually get one type. You don’t have to worry about assessing the quality of different brands and prices.
Greater assurance of quality: The OEM part should work exactly as the one you are replacing. It is what the vehicle was manufactured with and provides a peace of mind in its familiarity and performance.
Comes with a warranty: Most automakers back up their OEM parts with a one-year warranty. And if you get your car repaired at the dealer, they’ll usually stand by their labor as well.

Quality varies greatly: The saying “you get what you pay for” rings true here. Some aftermarket parts are inferior because of the use of lower-quality materials. Stick with aftermarket brands you’re familiar with or are recommended by a mechanic you trust, even if these parts cost a bit more.
Overwhelming selection: If you’re not familiar with aftermarket brands, the selection could be overwhelming, and there’s some chance you may get a bad quality part. Even a part as simple as a spark plug can be made by dozens of different companies and comes in numerous variations. Consult your mechanic for advice or simply stick with the OEM part when the price difference isn’t significant.
May not have a warranty: To keep costs down, some aftermarket parts are sold without a warranty.
