  • Brake Fluid

    For more than 126 years, Bosch has been developing motor vehicle systems. The development of braking systems has been equally comprehensive. Accordingly, all brake fluids have been tested to comply with the systems. At the same time, they meet the high demands placed on safety and quality.

    Rotating Machines

    The production of Bosch starters and alternators for the aftermarket is subject to the same stringent quality guidelines as the production of original equipment. The whole production process is controlled meticulously – from start to finish. As a result, each and every part features 100% Bosch quality.

    Gasoline Systems

    In 1887, it all started with the low voltage magneto ignition system for stationary engines produced by Bosch. Bosch has been working on and developing gasoline systems for over a century. This has resulted in high quality aftermarket parts such as ignition coils, spark plugs, and engine management components.
