The H.V.S. Sun Hyper Voltage System GT (*HOT INAZMA HYPER by Sun Automobile JAPAN)is designed to stabilize voltage in your vehicle for maximum battery efficiency, allowing its full potential to be released. H.V.S. GT Version provides both function and stylish appearance; units are designed to universal to fit any vehicle, with mounting brackets and one (1) additional grounding cables. The most secure and reliable mounting locations have been determined by our engineering and design team, to ensure an easy installation and excellent performance. An LED on the unit also operates as a system monitor, to alert you when your battery may need service or replacement.

Hyper Ground System (Type-S for Suby)

The new "Hyper Ground Wire System" is the safe and reliable generation tuning system that provides a low resistance ground path. A better ground gives more Torque,better Mileage, better Response, and better Starting Ability.This system provides direct ground path from battery negative to body, chassis, and engine components to give extreme improvement on electrical circulation. In addition "Hyper Ground System" cables have 10 times less impedance than factory ground systems which provides immaculate conduction to prevent electrical power loss.The higher resistance of factory grounds, effect the ignition system and obstructs the primary potential. The "Hyper Ground System" uses thick gauge 99.99% pure copper, and connects directly from the cylinder head and other points under the hood to the battery, to provide an ultra low resistance connection.This will increase the primary potential of regular cars to ignition tuned vehicles.

Package Included Battery Terminal clamp and 5 Hyper Ground Wires in the following size:
400mm(15.7in)
500mm(19.7in)
600mm(23.6in)
750mm(29.5in)
