The BMW Part Adjuster unit 11617579114, also known as the DISA (Dynamic Intake System Adjustment) valve, is a crucial component in BMW vehicles. This part is located in the lower portion of the intake manifold by the throttle body. Its primary function is to optimize the airflow into the engine, enhancing performance and efficiency.
By adjusting the length of the intake runners, it ensures that the engine operates at peak efficiency across various RPM ranges. This adjuster unit is found in several BMW models from 2006 to 2013, including the 328i, 528i, and X3 series. Its significance lies in its ability to improve engine response and overall driving experience, making it an essential part of BMW’s engineering excellence.
The BMW Part Adjuster unit 11617579114, also known as the Intake Air Adjustment Unit or DISA (Dynamic Intake System Adjustment) Valve, plays a crucial role in optimizing the engine’s performance by controlling the path of the air in the intake manifold. This unit adjusts the length of the intake runners, allowing either a shorter or longer runner length depending on the engine’s operating conditions. By doing so, it ensures that the engine receives the optimal amount of air for combustion, which improves throttle response, reduces hesitation, and enhances overall engine efficiency.
The adjuster unit is typically located next to the intake manifold and is responsible for regulating the airflow to the engine’s cylinders.
When the engine is running at low RPMs, the adjuster unit opens to allow a longer runner length, which helps to maintain smooth and consistent airflow. At higher RPMs, the unit closes to shorten the runner length, which increases the air velocity and improves the engine’s power output.
In summary, the BMW Part Adjuster unit 11617579114 optimizes the engine’s performance by dynamically adjusting the intake air path, ensuring that the engine operates efficiently across a wide range of conditions.
