Febi 11-61-7-579-114 Engine Intake Manifold Adjusting Unit Left DISA Valve

The Febi 11-61-7-579-114 is a precision-engineered intake manifold adjusting unit, commonly known as a DISA valve (Differentiated Intake System Actuator), designed for the left side position. This critical engine component optimizes airflow through the intake manifold by adjusting the runner length based on engine speed and load conditions, maximizing both low-end torque and high-RPM power delivery.

Key Features:

• Left side intake manifold adjusting unit for proper airflow optimization
• Direct OEM replacement part manufactured to Febi's stringent quality standards
• Vacuum-actuated mechanism ensures precise runner flap operation
• Durable construction designed to withstand high temperatures and engine vibration
• Restores proper engine performance and eliminates intake-related fault codes
• Replaces BMW OEM part number 11-61-7-579-114

This intake manifold adjusting unit is essential for maintaining optimal engine performance. A failed DISA valve can cause reduced power output, rough idle, poor fuel economy, and check engine light illumination. The Febi replacement unit restores factory specifications and ensures smooth operation across the entire RPM range.
