BMW Electronic Throttle Valve Body 13541503358 for 1 3 5 X Z Series - OEM Quality Aluminum Construction

This Electronic Throttle Body (ETB) is engineered for BMW gasoline engines, replacing traditional cable throttles with advanced electronic control. As a critical component of the engine air intake system, it precisely regulates airflow to optimize power output, fuel efficiency, and emissions compliance.

1. Command Reception: Accelerator pedal signals are sent to the DME engine computer
2. Integrated Calculation: DME computes optimal throttle opening based on multiple parameters
3. Motor Activation: Electric motor drives gear mechanism via DME command
4. Valve Adjustment: Throttle plate rotates to precisely control air intake volume
5. Feedback Loop: Integrated sensors provide continuous position feedback for closed-loop accuracy

• Precise electronic control for superior engine response and fuel efficiency
• Compact integrated design with motor, sensors, and electronics
• High-grade aluminum construction meeting OEM durability standards
• Restores engine power, smooth operation, and optimal fuel economy
• Maintains low emission levels through optimal air-fuel ratio control

Professional installation is recommended, including throttle adaptation using diagnostic tools (e.g., ISTA/D) to ensure proper DME parameter learning. This critical step prevents irregular idle conditions and warning light activation.
