OEM (Original Equipment Manufacturer) parts play a crucial role in the maintenance and repair of vehicles and machinery. Here's why OEM parts are important:
- Precision and Compatibility: OEM parts are designed and manufactured by the same company that produced the original equipment. This ensures a precise fit and compatibility with the specific make and model of the vehicle or machine. Using OEM parts helps maintain the original performance and functionality.
- Reliability: OEM parts are known for their reliability and consistency. Manufacturers invest in research and development to continually improve their products, providing customers with reliable components that contribute to the overall durability and longevity of the equipment.
- Ease of Installation: Since OEM parts are designed to fit perfectly with the original equipment, they often facilitate easier and quicker installations. Mechanics and technicians appreciate the simplicity and efficiency of working with parts that are specifically engineered for the equipment they are servicing.
- Quality Assurance: OEM parts undergo rigorous testing and adhere to the manufacturer's quality standards. This commitment to quality ensures that the parts meet or exceed the performance specifications required for the equipment. Customers can trust that OEM parts are built to last and maintain the integrity of the original design.

Bosch invented the first practical magneto, an early ignition electrical source, which provided the spark to ignite the fuel in most of the earliest internal combustion engines, and is still used in general aviation engines. Bosch's corporate logo to this date depicts the armature from a magneto. Bosch was an early manufacturer of Anti-lock Braking System (ABS), and as time passed, Bosch became a leader in such specialized fields as traction control systems (TCS), the Electronic Stability Program (ESP), body electronics (such as central locking, doors, windows and seats), and oxygen sensors, injectors and fuel pumps.
