The main machine factory buys from supporting production factories and sells them as after-sales repair parts. The quality is guaranteed, but the quotation is expensive. The original supporting production of the main engine is OEM, which is the same quality as the pure parts. The packaging is different, but the quotation is lower than the pure parts. However, due to the high quotation of original factory parts and fittings, many customers' cars will be replaced by auxiliary factory parts after the warranty period. Deputy factory a refers to the production factory authorized manufacturer to produce accessories, it marked with its name, also has its trademark, but did not produce manufacturer brand LOGO, it will write "applied to xx, xx model". These spare parts are usually produced in small factories, but there are also some large factories in the world.
As for the original factory parts that should be selected after all, the users can say that there are different opinions. Some users advocate the use of pure original factory parts, which can protect the machine to the greatest extent. However, some users also claim that, in addition to the important parts used in the original factory, some unimportant parts can also be replaced by auxiliary parts.
