When repairing the car, always ask the repair shop if the parts replaced are "original parts". The general view is that the original is excellent and the auxiliary is not good; However, this view is actually one-sided. It is possible to say that the quality of the original parts of some vehicles may not be better than the auxiliary parts, but the auxiliary parts must also have a reasonable price.

The reason is that car manufacturers (car enterprises) will strictly control manufacturing costs, and some car enterprises are really broken; BAIC is a representative, but not the only one. It can be said that most joint venture vehicles have this feature. For example, for a well-known joint venture van brand, the parts produced by the manufacturer will be divided into grades 1, 2 and 3, and the price will naturally be from high to low.

This van company basically chooses second-class products. Some first-class products are supplied to other car enterprises, and some will enter the auto parts market together with third class products, because repair garages also need high standards and low registered accessories. Most users with high requirements for insurance vehicles use first-class products, and vice versa.

Are original parts really good? The quality is different. Under the same raw materials, products made from different moulds are different. In terms of accuracy, the original parts still have the right to speak. At present, the technical development of auxiliary parts is gradually shrinking from the original parts.

There is still a difference. Sales channels are different. The original parts are generally sold in the automobile 4S stores, central warehouses and spare parts warehouses, while the auxiliary parts are everywhere. As long as the price is appropriate and the quantity is large, anyone can sell it. Consumer purchase advice, if it is an engine or gearbox.

Where is the quality of the replacement parts of the transmission system or the original parts recommended? If it is a sheet metal part, auxiliary factory parts are also a good choice in the case of poor economic conditions and less particular people. The performance and quality of loading parts are higher requirements for the whole vehicle.

The pre-sales warranty period of new cars is basically three years or 100000 km. The quality problems during this period will not only affect the brand image, but also cause additional losses. Because the replacement of parts during this period is free of charge, the quality of the assembly parts must be reliable and durable.

Genuine parts are only parts processed and produced externally by automobile manufacturers, with low production efficiency, or some parts are processed by manufacturers with technical advantages to improve production capacity and quality. Of course, these manufacturers are all certified by the host manufacturer, and they have certain quality guarantees when signing production contracts.

That is, the three guarantees policy, which is generally 30000 kilometers a year. The auxiliary accessories on the market are good and bad, some are highly imitated, some are "three no", and there is often no quality assurance. Be careful when purchasing, it is difficult to deal with problems, and technical supervision is also troublesome, especially for important parts of the suspension chassis.

Of course, it is not a one shot kill. Some suppliers also have a certain production capacity, but without the certification of the OEM, they cannot use the logo. There are no three products, so the price is much cheaper. If it is really good, how can there be serious abnormal noise, suspension wear, engine wear and transmission fluid leakage.

Even the core supercharger, torque converter or clutch friction plate is quickly damaged? These problems generally occur in joint venture vehicles and some domestic vehicles of the third and fourth line. The original parts generally refer to those produced by regular manufacturers, not the original parts. Auxiliary parts are generally produced in small factories.

The mold is not as precise as the original factory, and the materials used are also worse than the original factory. You can also use high. As for the price, it must be a world of difference. The more expensive part must be the original parts. For example, does Valeo supply BMW to increase profits? BMW supplies the 4S store.

Is it to increase profits? If the 4S store sells it to the car owner, will it increase the profit? So original parts are more expensive. The original parts are directly provided to the after-sales market by the supplier.
