What is the Difference Between OE and Aftermarket Parts?

Aftermarket and OE parts are terms many people may be familiar with but not fully understand. When the time approaches to replace parts in your vehicle you may be faced with the choice of using either aftermarket or OE parts, and it’s important to understand what the difference is.

What is an OE/OEM Part?

OE simply stands for Original Equipment, while OEM stands for Original Equipment Manufacturer. An OE part is created by the original manufacturer of a vehicle, built specifically for that application. All of the components fitted to a brand new car leaving the factory will be OE.

OEM signifies a part created by an authorised manufacturer of that part. These are used as replacements for when the OE part fails. These will typically be fitted by the car manufacturer’s official technicians, but they can also be available from a local garage if they are OEM certified.

What are Aftermarket Parts?

Aftermarket parts are manufactured as a copy of the original. They are not associated with the original manufacturer and are sold as a cheaper alternative to replace the OE part. A good aftermarket brand will reverse engineer the OE part and work out ways to improve upon it.

Pros and Cons of Aftermarket Parts?

Pros

Price

Aftermarket parts are a much cheaper alternative to OEM. When it comes to certain costly repairs it is always ideal to reduce the cost as much as possible. Use of aftermarket parts, which tend to be at least half the price of OEM, can greatly reduce this burden. Additionally, most insurers will prefer this option to reduce costs.

Availability

There is a wide selection of parts available today in the aftermarket and this freedom of choice is a huge benefit. Not only does this competitive space allow for more variety and cheaper prices, it is also more convenient to get the parts. An OEM part will need to be ordered specially and may take time to arrive, while most aftermarket parts are available for next-day or same-day delivery. One may already be available from a local motor factor or garage.

Quality

Quality always varies, especially when there is so much choice. However, a lot of parts available in the aftermarket meet OE standards with some even exceeding them.

Cons

Quality

While there are a lot of OE quality parts available, the variety does mean that there will be parts that do not live up to the original and may even fail prematurely.

Warranty

Usually, all OEM parts come with warranty as standard. However, not every aftermarket part comes with a warranty.
