Distinguish auto parts: Genuine, OEM and Third Party

Car advice

It is very important to distinguish auto parts. Because the incorrect replacement or poor quality will affect the operation of the vehicle.

Currently, on the auto parts market, there are 3 main types:

Genuine parts
OEM Parts – Original Equipment Manufacturer
Spare parts from 3rd party – Aftermarket.

Genuine parts 

Genuine parts are auto parts that are attached to a vehicle during factory assembly. In a nutshell, when a wheelchair rolls off the production line at the factory, all the parts and accessories attached to the vehicle are genuine parts (original parts) of that vehicle.

Original parts are also provided to the genuine repair and maintenance agents of a car company with the brand’s logo printed on the parts accompanying the vehicle’s distinctive packaging and packaging codes.

Due to the additional costs of brand name, clear genuine origin as well as a high quality assurance factor, genuine parts often have the highest price among spare parts (excluding custom parts. specialized, high performance for individual needs).

Parts cost is also a part of the reason that genuine maintenance costs are always higher than when done in external car garages. In return, customers enjoy genuine warranty for those parts as well as have peace of mind about origin and quality during use.

OEM Parts – Original Equipment Manufacturer

The first thing you need to know is that OEM (Original Equipment Manufactured) and OES (Original Equipment Supplied) are two quite similar concepts, with almost no difference.

OEM parts are parts manufactured by the same genuine parts manufacturers with the exact specifications and compatibility of each vehicle model. However, the attraction of this type of parts is its cheaper price (about 30%) compared to genuine parts.

Does the reason for this come from the “non-genuine” nature of the OEM product?

Although made by the manufacturers of genuine parts, OEM parts do not undergo rigorous testing according to the standards of each car manufacturer, but only be tested against the standards of the OEM manufacturer. usually lower than the genuine standard).

Therefore, OEM parts will not have a part number stamped as genuine. The part number parameter contains information about the production time, product line, … from which clearly shows the origin and quality assurance of a genuine spare part product. This also means that OEM parts are not packed with genuine logo, not packaged according to genuine standards with full information and car manufacturer logo.

Because there is no genuine logo (no part number), not packed with logo and specifications according to the company, no genuine logo, quality inspection is not too strict like genuine goods, no part number code ( date of manufacture, production line, …) – part number shows the clear origin and quality of a part product.

Why is it possible that a single part has many different OEMs?

Automakers must have a secondary supply of parts (such as multiple suppliers) for a certain type of parts so that there is no problem with any one supplier. loss of car manufacturers’ manufacturing capabilities and allowing replacement of other brands for new products and for warranty and repair replacements.

For example, the VDO pump is an original accessory that can be mixed with a Bosch pump with the same features, the ZKW fog lamp can be replaced with a Hella lamp, or the Balo brake is replaced with Zimmermann.

Aftermarket parts

Conventional aftermarket parts are also manufactured on precision machining machines with the same materials and specifications as genuine. But sometimes the appearance of the part does not have to be exactly the same as the original part because the manufacturers of the exterior parts do not follow the supplier’s design.

Why aren’t there aftermarket parts for new cars?

Most vehicles will require some repair work in the first and second year. And many of the parts for these repairs are only available through car dealerships.

Often OEMs cannot sell parts for new vehicles in, into the aftermarket (by agreement), until a few years later. This restriction allows car manufacturers to recoup the costs of their equipment. Even so, it is only in your interest for replacement purposes within the vehicle warranty period.

Quality depends on each case?

  • If you only need a more attractive price than the two above, the quality will not be guaranteed.
  • On the contrary, there are some companies that, apart from manufacturing spare parts, also have their own designs to improve product quality. Genuine products usually only meet the general needs of the majority of customers at a relatively basic level. Therefore, the high-end aftermarket parts still have their own place in the market when focusing on the minority of customers with special needs such as off-road, high-speed running. customary in the racetrack, super luxury
