Installed by the shop for a list price of 33,000 yen. Installed on an X-Trail, but may be usable on other car models. ■ Cryogenic treated grounding cable. ■ One cable from the negative terminal of the auxiliary battery to the genuine ground point on the body. ■ One cable from the engine room, body ground to the engine block. ■ Effective set of two cables. Non-resistor cables are grounding cables that minimize electrical resistance. It is said that by cooling metals to extremely low temperatures, they can reach a "superconducting" state where electrical resistance approaches zero. This technology is called "cryogenic treatment" and is used in a variety of applications, from advanced industrial products such as space shuttles and medical equipment like MRI, to superconducting linear motors, as well as for increasing the strength of blades, tuning wind instruments like trumpets, and in audio cables.
