The products in the selection are divided into four categories:

1. Original parts (OE)
   Parts that are installed by car manufacturers for initial assembly are mostly in the car manufacturer's original packaging.
2. Original parts for after-sales service to brand agencies (OE Service and also OEM Service Parts)
   The products are intended for use in brand services, and their production complies with the requirements for first-time installation parts. The products may differ from the products originally installed on the car (modified or unified). Several different products are replaced by one, or the quality of the products is changed. For example, instead of several different radiators, one more universal one is left in use in order to reduce the number of products kept in production and in the warehouse. Such products are usually put into production 1-3 years after the car brand's model is released. Such products also replace OE products when OE products have developed design or durability defects. Products may be packed in bulk packaging (several products in one package and therefore may not have the OE logo individually).
3. Products packaged by the original part manufacturer (OEM)
   The products come from the same production line as the OE products but are not packaged in packaging with the Automaker's logo. Mostly in the manufacturer's own packaging or so-called anonymous packaging. The products themselves may have car brand logos and product codes (mostly removed). The products are also packed in the customer's packaging (product brands).
4. Aftermarket or so-called B-parts
   The products are of very different quality. Some of them exceed the quality of original parts, but mostly the agreements set by international standards are followed. Quality products and their manufacturers in this group have international certificates and are recognized by special recognition companies (e.g., ISO, TÜV or TÜV Thatcham, and TÜV Rheinland) or have the approval of car manufacturers. The quality of the products in this group depends on the manufacturer, the customer, and his/her goal in marketing the given products (whether the standards are exceeded or simply met).
   NB! The price level in this group does not guarantee quality in any way. A more expensive product is not necessarily better than a cheaper one. There are many so-called brand packers operating in this group. The packaging of a well-known brand can contain the same product as the packaging of a lesser-known brand (the only difference between packaged products can often be only the price level and packaging design). There are thousands of times fewer manufacturers than packers. You should not be afraid if the manufacturer has proudly added, for example, Made in China to the packaging. Almost 99% of car manufacturers are related to this country! The majority of car parts or their components are also produced outside EU countries. For example, South Africa, Argentina, Brazil, Mexico, Canada, USA, Taiwan, Japan, South Korea, Malaysia, Australia, China, India, Pakistan, Turkey, Egypt, Russia etc. The location of the country of manufacture or the location of the manufacturing plant in the current globalization process no longer determines quality. The quality is determined by the agreement between the MANUFACTURER and the CUSTOMER on the quality of the product and the materials used for its production!

The catalog is also built with quality in mind. For us, it is not the manufacturer or the manufacturer's package/packer that is important, but the quality of the product itself. For insurance works, it is recommended to choose products with quality 1-4 or the Green and Yellow zone. Red zone products are a good "B" group but with a very uneven quality level. A higher-quality product can sometimes be even cheaper; therefore, we ask you not to be guided by the popular rule "the more expensive product is always better" and "the well-known brand is always better". Unfortunately, this is not the case.
