Power Steering Pump.

The BOSCH Power Steering Pump is a vital steering system component designed to generate the hydraulic pressure required for the vehicle’s power-assisted steering system. Driven by the engine, the pump circulates power steering fluid through the steering rack, significantly reducing steering effort and providing smooth, precise control during manoeuvring, parking, and everyday driving.

Fits:

  • Porsche 958 Cayenne S V8 4.2L Diesel (382Hp) 2010-17
