      Bosch has been a major supplier of new alternators and starters to OE vehicle manufacturers since 1913. Securing OE certification requires strict adherence to stringent precision and performance criteria. These same exacting criteria are also applied in the manufacturing of all Bosch aftermarket alternators and starters. Whether 100% remanufactured or new, Bosch Premium Alternators and Starters are quality built and 100% factory tested to ensure years of reliable performance, even under the most extreme operating conditions. That's why they are preferred by more professional installers.
