Genuine Auto Parts

What does genuine auto parts mean?

A genuine part is a component that was installed in your vehicle when the vehicle was first manufactured. Genuine parts are more expensive than other types of auto parts because they carry the company logo.  

Is genuine the same as OEM?

Original equipment manufacturer (OEM) parts are parts made by the manufacture or made for them to their specification. Genuine parts are parts supplied by the vehicle manufacturer in their packaging. Some vehicle parts can be purchased directly from the OEM.  

What is a genuine replacement?

Genuine parts are the original parts that were installed on your vehicle when it was manufactured. Therefore, genuine parts will have the manufacturer’s label, come in the manufacturer’s packaging and cost more because of their genuine status.   In simple terms, Genuine auto parts are what they say they are, and they are the most expensive car parts on the market.  

OEM (Original Equipment Manufacturer) Auto Parts

What do OEM parts mean?

OEM stands for original equipment manufacturer…. OEM parts are generally going to be your best option more often than not because the OEM designs both the vehicle and the part. The same design specs are used and the same factory makes the part, which means there will be less of a discrepancy from part to part.  

How do I find out if something is OEM?

If you’re looking for OEM parts, then these are the same quality as genuine parts and can be identified from their company branding. Unlike genuine parts, these come in boxes branded in the name of the company that manufactured them. In terms of price, they are relatively cheaper as compared to genuine parts.  

Is it worth getting OEM parts?

When choosing parts, OEM parts are more expensive, but are easier to choose and usually are backed by warranty (do your own due diligence if they offer and for how long) . Aftermarket parts are equal to or better than the OEM part. If the price seems too good to be true, beware of poor quality parts.  

In simple terms: When you order genuine OEM parts, you’re getting the best parts available, but since they don’t carry the manufacturer’s branding, they’re more affordable than genuine parts. They’re also easier to get since more sellers would be willing to keep them in stock.

Aftermarket Auto Parts

Why is it called aftermarket parts?

Aftermarket parts are brand new replacement parts made by a third-party manufacturer. They might not be the same quality or fit as the original parts.  

Are aftermarket parts good?

There are many high-quality aftermarket parts available that are as good as OEM parts, or in some cases, can perform better. Be sure to ask your mechanic about your options.

Do aftermarket parts decrease value?

Aftermarket upgrades and installation of auto parts, can have a significant effect on the value of your vehicle. Too many upgrades, however, and you may find that you’ve actually lowered the overall value of the vehicle, despite the combined value of the upgrades.

In simple terms: When choosing these kinds of parts, it’s best to do your own research. You can do that by talking to your mechanic, looking online or even asking your friends and family. They will be able to give you advice on which aftermarket parts will work best for your make and model.
