Easily upgrade your BMW's main ground cable with this direct replacement ground cable! As your vehicle ages and is exposed to the elements, the factory unshielded ground cables become corroded and often lead to electrical issues. These upgraded ground cables are made from 2 AWG sealed copper welding cable with tin-plated copper lugs and sealed with high-temperature and high-wear resistant heat shrink to keep water out of the cable. These cables are designed to withstand all types of weather and environments while resisting corrosion for years to come.
