URO 11617579114 Engine Intake Manifold Adjusting Unit Left DISA Valve

The URO 11617579114 is a left-side intake manifold adjusting unit, commonly referred to as a DISA valve (Differentiated Intake System Adjuster). This component actively controls airflow within the intake manifold by opening and closing an internal flap to optimize engine performance across different RPM ranges. At lower RPMs, the valve restricts airflow to increase intake velocity and improve torque, while at higher RPMs it opens fully to maximize airflow and horsepower.

Key Features:

• Direct replacement for BMW OEM part number 11617579114
• Left-side (driver side) intake manifold position
• Controls variable intake geometry for optimized performance
• Precision-engineered to OEM specifications
• Includes actuator mechanism and mounting hardware

A faulty DISA valve can cause rough idle, reduced power, check engine lights, and rattling noises from the intake manifold. This URO replacement unit restores proper intake manifold operation and engine performance.
