The Pierburg Turbocharger Boost Solenoid - 700887200 is a component used in turbocharged engines to control the amount of boost pressure produced by the turbocharger. It is responsible for opening and closing the wastegate, which regulates the flow of exhaust gases to the turbine and ultimately controls the boost pressure. This solenoid is designed to be durable and reliable, ensuring consistent performance and efficient operation of the turbocharger. It is a crucial part of the engine's overall performance and should be regularly maintained to ensure optimal functioning.
