Hot rodding and car modification are something of an American pastime. It began already in the 1920s in Los Angeles and continues to evolve over time.

Obviously modding is not an exclusively American phenomenon. Drivers all over the world try to squeeze a little more performance out of their beloved cars.

As a BMW driver, you know a thing or two about performance. Your car is among the most agile on the road and you know it is thanks to the high quality BMW components.

However, you may not know the difference between OEM and aftermarket parts. Here’s everything you need to know about this important distinction and how it can affect you when you need BMW spare parts.

What is the difference?

“OEM” stands for “original equipment manufacturer”. In the automotive world, OEM parts are new parts built by your car manufacturer. They are identical to the parts with which your car first came off the assembly line.

Aftermarket parts are not designed by your car manufacturer. Instead, they are made by a third party with the hope of replicating or improving the OEM parts.

Aftermarket parts may not always be designed to the exact specifications of an original part, but they are usually very similar.

Which one should you choose?

Whether you should opt for OEM parts or aftermarket parts is entirely up to your personal preference. There are distinct advantages and disadvantages to both options.

Advantages of aftermarket parts

If your goal is to improve your car’s performance, aftermarket parts are the way to go. Many aftermarket auto parts, like turbochargers and exhaust systems, can offer substantial performance improvements.

They can also be used to enhance the look of your vehicle. Things like side skirts and hood scoops may only offer negligible performance gains, but they make your car unique.

There is also a wide variety of aftermarket parts to choose from. Shopping around for aftermarket parts can save you money.

Advantages of OEM parts

Since OEM parts are made specifically for your car, you can always trust that they will be a perfect match. There is no guesswork when it comes to their quality and reliability.

It’s easy to choose an OEM part, as you’ll likely only have one option. In some cases, they may even come with a guarantee.

Disadvantages of aftermarket parts

While there are many reasons for choosing aftermarket parts, they have some downsides.

Aftermarket parts are not designed specifically for your car model, so they may not be a perfect match for your car.

Also, the quality of aftermarket parts can vary. Some are as good or even better than OEM parts, but you’ll need to do your research or consult a reputable mechanic to be sure.

Disadvantages of OEM parts

OEM parts have their own small list of drawbacks.

Most OEM parts are more expensive than comparable aftermarket parts. Also, the supply is limited due to manufacturing specifications.

They are also harder to find, as you can only buy them from a dealership or authorized shop.

Where to find BMW Performance parts

Now that you know the difference between OEM and aftermarket parts, you can shop with confidence.

If reliability is your concern, you may want an OEM part. However, if you are looking to improve the performance of your car, aftermarket parts are for you.
