 WHAT AUTO PARTS TO CHOOSE? The genuine or a substitute with aftermarket?

What we call the genuine parts?

Throughout the world scattered manufactures, capable of producing certain parts for automobiles. Some of them have a fairly high quality products and receive orders from automotive companies. Let's say, «Volkswagen-Audi AG» has ordered ten thousand BOGE shock absorbers. Of these, seven thousand will be installed on the machine. The remaining three thousand intended for "after sales service" that is, repair. They are packaged in boxes marked with VW and disperse Warehouse regional dealers Volkswagen waiting in the wings. These parts we call genuine. But the story does not end there. The BOGE, to execute the order, continues to produce these dampers makes two thousand. They are packed in the box with the inscription «BOGE» and sell to wholesalers. Quality, naturally, the same, but the price is lower by 1.5 - 2 times. Besides BOGE, their produce to the markets SACHS, within the same industrial group. In addition, the BILSTEIN plant also buys Volkswagen documentation and begins to produce high-quality shock absorbers, the resource of which, for example, is higher than that BOGE, and, therefore, than the original. However, car manufacturers have recently issued a license to manufacture competing shock a few years after the start of the sale of the genuine, but in recent years the tendency of "acquiescence" in the parallel sale non-genuine parts. In addition, and any factory, let's call it GUNESH, without buying any documentation and licenses begins to produce the same shock. All of these shocks - unoriginal, ie sold through the channels of manufacturers parts.

Is it true that all the original auto parts better?

The answer follows from the previous one - non-genuine parts can be better than the genuine (BILSTEIN), completely identical (BOGE), equal in quality (SACHS), or worse (GUNESH). At the same time, as a rule, they all have a price lower than the genuine. Genuine in this case - the one that was installed on the factory assembly line.
Another misconception is ubiquitous: the item for BMW better to book in the store that calls BMW, Mazda item for the store MAZDA, etc. Intuitively, this is understandable, but - not true. When repairing machines or buying parts it is quite logical - the master will save you a lot of time, if just to know what, where and how screwed. But when you order any prior knowledge not taken into account - is always a chance to make a mistake, you need anyway to look through catalogs. And work with catalogs - a special art, and here it is necessary knowledge of several languages ​​and used abbreviations, and software, and the principles of design catalogs and more that is given by years of work in the delivery system. Anyone who works with catalogs, knows even knowing the vehicle's VIN, often still have to choose between multiple choice items, and on a variety of grounds. The notes can be anything from "the shaft 1.37 inch thick" (climb and measure!) And ending with profound "for gear pairs with a larger angle of sharpening the teeth" (and what was not increased?).

It should be borne in mind that when the term of the removed parts to manufacture more than 8 years, stores are trying to "reset" its in wholesale sales. Therefore, the probability of failure of the genuine parts for cars that do not produce more than 8 years, is markedly increased.

Is it always a filed auto part - a fake?

Oddly enough, no, not always. The market for auto parts is very complex and at first sight sometimes paradoxical. For example, a lot of paradoxes brings the fact that often one and the same plant produces the same item at the same time in three persons:
as the original manufacturer's assembly line for car
as the original aftermarket
as a non-original (replacement), ie intended to be sent to their own packaging wholesalers
But sometimes it turns out that the parts manufactured and labeled in one embodiment, it is necessary to shift to another direction. This raises the risk of violating the strict European laws on trade marks - and in the course of going

What directory to use?

In fact, it seems unlikely that large, reputable suppliers of spare parts allow mistakes in their catalogs. Indeed, the error is not in their catalogs, but ordering them, it is possible to bring the wrong item. Let's concern GKN-Spidan learned to make good drives the wheels. Suppose, Nissan Europe has ordered his half-line for some of its models, assembled at the plant in England. Naturally, Spidan persuaded them to give him a license and to sell them as after market and immediately included them in the catalog. In addition, he bought the documentation included in the catalog and a few other types of drives Nissan, which, as it seems, will be in demand from wholesalers. But here's the rub! In addition Spidan spindles, the factory Nissan in some parties have used the previous, say from the GLO. In addition, the left steering wheel model with the same name was produced in the homeland and Nissan, in Japan, but there were already third axis, from HDK. And on a separate assembly line going version Gulf Corporation (the Emirates), and there also had their differences, caused by purely supplying reasons. And in England, a small party was a version with a larger engine capacity, which it was decided to put the drives from another model. And so on. It is not an exaggeration. In life, usually more difficult!

Of course none of these options to the catalog Spidan not fall, they have no relationship, and he said to them simply - do not know. There will be shown only those species that produces itself Spidan. Therefore, the safest way - to find a piece of the original catalog and on the original article to seek substitutes.
