1. Look at the packaging. The packaging of original accessories is generally more standardized, with unified standard specifications, and the printing is clear and formal, while the packaging and printing of counterfeit products are relatively poor, and it is often easy to find flaws from the packaging;

2. Look at the color. Some original accessories have a certain color on the surface. If they meet other colors, they are counterfeit and shoddy parts;

3. Look at the appearance. The original parts are printed or cast and marked clearly and formally, while the counterfeit products are rough in appearance;

4. Look at the paint. Unscrupulous merchants simply process waste parts, such as dismantling, assembling, assembling, assembling, painting, etc., and then sell them as qualified products to illegally obtain high profits;

5. Look at the texture. The materials of the original accessories are qualified materials according to the design requirements, and the counterfeit products are mostly replaced by cheap and inferior materials;

6. Look at the craftsmanship. Although the appearance of inferior products is sometimes good, due to poor craftsmanship, cracks, sand holes, slag inclusions, burrs or bruises are prone to appear;

7. Look at "storage" If there are problems such as dry cracking, oxidation, photochromic mirror or aging of auto parts, it may be caused by poor environment during storage, long storage time, poor material itself;

8. Look at the "engagement" If the rivets of the clutch plate are loose, the brake hose is degummed, the joints of electrical parts are desoldered, and the joints of the paper filter element are disengaged, etc., it cannot be used;

9. Look at the logo. Some regular parts are marked with certain marks, such as the time gear mark, the piston top mark and other assembly marks, which are used to ensure the correct installation of the parts, and those without which cannot be purchased;

10. Check for omissions. Regular assembly components must be complete and intact to ensure smooth loading and normal operation. Individual small parts on some assembly parts are missing, usually "parallel imports", which cause difficulties in loading. Often due to the shortage of individual small parts, the entire assembly parts are scrapped;

11. Look at the protective layer. In order to facilitate storage and prevent parts from being bumped, there is a protective layer before the parts leave the factory. For example, bushes, large and small bearing bushes, pistons, valves, etc. are generally protected with paraffin wax to avoid damage to their surfaces. If there is no protective layer on the surface of these important parts, they are mostly "parallel imports";

12. Look at the certificates. Some important components, especially assemblies, such as carburetors, distributors, generators, etc., usually come with instructions and certificates when they leave the factory to guide users in installation, use and maintenance. Fake and shoddy products;

13. Look at the specifications When purchasing auto parts, it is necessary to find out the main technical parameters, and the special technology must meet the requirements for use. Some counterfeit and shoddy products have almost the same appearance as the real ones, but they are not suitable for installation, either larger or smaller, and they are always unsatisfactory to use, leaving hidden dangers of accidents.

14. The test report issued by a third party can not only prove the authenticity, but also show its quality.
