On ebay you can buy something for almost 100 bucks thats a box with some flashing led lights and a hand full of 8 gauge wires you mount under the hood and to both battery leads. The tear downs shows its a cap inside. The wires basically help ground the stuff under the hood the cap helps to filter noise.
