Orbital Power Module M4 with 2 ferrite cores, used. I have two of these, one for each of my cars, but I removed one because I sold a car. They were installed for two years. I can feel the effect, so I have also installed various other Orbitron products on my other car. Product Description Make your car or motorcycle even more exciting and fun! Orbitron utilizes energy-generating materials that use natural minerals found in nature. By combining several natural materials that generate energy and further increasing that energy with more catalysts, we have succeeded in drawing out the original performance of the vehicle by reducing static friction (resistance) from the car body. When this static electricity is neutralized and reduced, the sliding resistance caused by mechanical friction decreases, and even the friction generated by air friction can be reduced. This power module is the core center device of Orbitron products. It is a self-energy-generating type, and by connecting it to the negative terminal of the battery, it continuously supplies a large amount of electrons to the vehicle body immediately. There are changes such as smoother revving, torque and power up, improved audio sound quality, reduced wind noise, and a more supple suspension.
