Automotive Parts: Comparing OE, OEM and Aftermarket Components

OEM, OE, and Aftermarket Parts - AAZ Blog

If you are planning on performing major repairs or servicing on your vehicle, you will require new automotive parts. In general, there are numerous options to consider for purchase, depending on your vehicle's requirements, your budget and personal preference. Below is a brief comparison of your main new auto part options: OE, OEM and aftermarket.

Original Equipment (OE)

Original equipment refers to auto parts which are designed and fabricated as the original components in your vehicle. These products are branded as official merchandise from the manufacturer of your vehicle. For example, BMW parts will come in BMW-marked packaging. OE parts are sold through authorized dealerships.

Original Equipment Manufacturer (OEM)

Car manufacturers often outsource the manufacture of vehicle parts to Tier-1 suppliers and advanced fabricators. Like OE parts, OEM replacement components are exactly the same as the original parts installed in your vehicle. However, they are branded according to their actual manufacturer such as Bosch instead of having the official marking such as BMW.

Aftermarket Auto Parts

Aftermarket auto parts are not manufactured by companies connected to the original car manufacturer. They are normally fabricated by third-party suppliers. The cost of aftermarket parts is considerably lower than the OE and OEM parts, but may or may not include a warranty. The quality of the products is often the same, but can be significantly higher or lower than OEM parts, so it's important to buy from a trusted company. In addition, with aftermarket parts, you can purchase unique auto parts to change and upgrade the performance of your vehicle.
