I actually felt the effects myself. The following is quoted from the manufacturer's website: While a vehicle is running, static electricity is generated by the friction between the air and the vehicle body, which becomes friction (resistance). The m+ FRICTION FREE MODULE 4-LAYER is a product that enables smooth and comfortable driving by reducing this friction caused by static electricity. By combining multiple materials that release energy into a four-layer structure, it efficiently generates electrons and carries the electrons throughout the vehicle body through the body earth, neutralizing and reducing the static electricity charged in each part. Effects such as smoother engine feel, easier low-speed driving, and improved ride comfort can be expected, and it also reduces the adhesion of dust due to static electricity, so it also has the effect of making the vehicle and equipment less likely to get dirty and keeping them clean. Because the vehicle's movement feels smoother, it reduces fatigue during long-distance driving and long-hour driving, making safe, comfortable, and enjoyable travel possible. It is a product that improves not only driving performance but also sensory performance and comfort performance. Regardless of the vehicle model, installation is completed simply by connecting it to the negative terminal of the battery, and it will continue to be effective semi-permanently. After installing the product, you may feel a slower deceleration even when you release the accelerator, so please be careful about the distance between vehicles, etc.
