The Bosch Throttle Body Kit - 472075 is a comprehensive set of products designed for use in a car's throttle body system. It includes three essential components: a throttle body, an air intake hose, and a throttle position sensor. These parts work together to regulate the amount of air entering the engine, ensuring proper combustion and optimal performance. The throttle body is responsible for controlling the opening and closing of the throttle valve, while the air intake hose delivers clean air to the engine. The throttle position sensor measures the position of the throttle valve and sends this information to the engine control unit, allowing for precise fuel delivery. This kit is a convenient and cost-effective solution for maintaining and repairing a car's throttle body system.
