There are two main types of auto parts available on the market: OEM, or Original Equipment Manufacturer parts, and aftermarket parts. The main difference between the two types is that OEM parts are made by the same company that makes the car, and thus are designed for that car model, while aftermarket parts are made by third party companies. However, there are further differences between these two types of car parts, and understanding such differences allows you to choose the right type of parts for your car.

OEM Parts

OEM parts are made by the car maker and thus are guaranteed to fit your car. They will not void your warranty if you have them installed, and they are most commonly used at dealership service stations. OEM parts make replacing a part in your car very simple, as you do not have to compare prices and brands. You are also given a greater degree of quality, as the part that you replace is made specifically for that car, and is identical to the replaced part. OEM parts also almost always come with a warranty, which will allow you to get the part replaced for free if it breaks again.

However, it is important to note that OEM parts will come with a high price tag, and can only be bought from a dealership, which means you can't look around for the best price on the part. Additionally, you should remember that just because it is made by the car maker doesn't mean that it is the best part available. Some aftermarket parts can outperform OEM parts.

Aftermarket Parts

Aftermarket parts are much less expensive than OEM parts because they are made by third parties. You can look around at various dealers to find the best price available for a certain part, and this also means that it is very easy to find the right part for your car. Additionally, aftermarket parts can outperform OEM parts in some instances, depending on your car, the part chosen, and the actual manufacturer.

However, it should be important to note that the quality of aftermarket parts varies greatly, as there is no standard that the part has to meet. Also, it can be hard to choose the right brand, as there are literally hundreds of different manufacturers who all make the same part. Finally, aftermarket parts don't always come with a warranty, which means that you run the risk of the part breaking and you having to purchase another part out of your own pocket.
