> What amp certified jumper cables do we need for an '08 X5?


When it comes to jumper cables, bigger conductors are always better, as long as the clamps on the ends are still small enough to work on the jumper terminals.

Personally, I use 4 gauge 12 ft cables in my vehicles. In some cases I wished I had 16 ft cables, but typically 12 ft is enough for most situations.

Here's a sample of what's out ther:
