ECS Tuning Heavy Duty Ground Cable Upgrade (12427549396)

If you're experiencing electrical issues, hard starting, or flaky charging, your engine ground strap is a likely culprit. The engine ground strap is a thin, non-insulated cable that spans from the left engine mount arm to the frame horn. Despite the seemingly ordinary nature of this part, on aging chassis, it is known to cause massive headaches. Due to its non-insulated design, years of exposure to water, dirt, and road salt will cause the wire to corrode, ultimately leading to complete failure. A break in this cable will cause an open circuit, resulting in issues with the vehicle's electrical system and potentially leading to a no-start condition.

To solve this issue, we've engineered an exact-fit, upgraded ground strap for your E9X BMW! Unlike its OEM counterpart, our design features insulated, large-gauge copper wire for dependable conductivity and long-lasting durability. Additionally, factory-style lugs are zinc-coated, crimped, and soldered, ensuring protection against corrosion and oxidation.

Whether you're replacing a visibly corroded strap or proactively preventing failure, our in-house engineered solution is sure to provide lasting performance and protection.
