Best choice for spark plug (ignition) wires?
The basic Bosch or Motorcraft plug wires are fine for your application. The el-cheapo wires won't cost you any power, they just won't last as long before you get misfire. Cheap wires may last a year, expensive wires may last 4 or 5 years. If you get a set of cheap wires with a lifetime warranty, you can get another set when they wear out for free. Just save the receipt.
Modified or race applications call for the expensive wires. When ignition output is increased by using a high-po coil, wire dielectric withstand voltage must be increased as well. This prevents the spark energy from arcing over to the engine block. Thats why some performance wires are 8 to 10mm in diameter- for higher voltages produced by high output coil. The actual power supplied to the plugs is controlled by the coil, not the wires. The resistance wire in sparkplug wires is used for EMI/RFI noise suppression. It doesn't affect power handling ability. In fact, MSD boxes state to NOT use with solid-core race wire. The RFI static messes with the MSD's little brain.
