This FEBI BILSTEIN wheel speed sensor, part number 172161, is designed to provide precise rotational speed information for each wheel. Accurate wheel speed data is crucial for the proper functioning of anti-lock braking systems (ABS), electronic stability control (ESC), and traction control systems. By monitoring the speed of each wheel, these systems can detect and prevent skidding, improve braking performance, and enhance overall vehicle stability. Manufactured to meet stringent quality standards, this sensor ensures reliable performance and durability. Its direct-fit design simplifies installation, making it a straightforward replacement for your original component.
