BMW Z4 Horn

Drivers are provided with an immediate audible warning with the BMW Z4 Horn to make traffic situations safe. Located low in the nose of every Z4, the Horn emits a sharp beep that easily cuts through the wind and engine sound so other cars and pedestrians notice the sporty roadster immediately. When the steering-wheel pad is pressed, this closes an electrical circuit and energizes an electromagnetic coil that makes a metal diaphragm vibrate and produce sound. This is the familiar electromechanical method that has been in constant use for generations. The early Z4 runs applied a single high-pitch unit. Later models, however, received a dual-tone pair which integrates a high-pitch note and a low-pitch note. Together they produce a broader, richer sound that is more effective and attention-grabbing. Further, they also make for an upgrade which changes the mixture of volume and timbre but not the basic operation. Regulations set minimum decibel levels, so BMW tuned each Horn to meet the rules without being too harsh in the cockpit. Compact housings maintain a fresh front-end outlook while easy-plug connectors allow owners to plug out worn parts easily. Designed to endure years of open-top driving, the durable construction resists water spray, keeping the Horn in good working order. Overall, BMW made sure that the Horn is reliable and audible.

If you are looking for OEM BMW Z4 Horn, we highly recommend to shop with us. Not only do we offer budget friendly prices, but we also provide fast delivery. In addition, we have a hassle-free return policy on all genuine BMW Z4 Horn that come backed by the manufacturer's warranty.
