In the process of the cooling overhaul, the one part I broke was the spark plug wire holder. 16 year old brittle plastic. I looks like new wiring sets come with the holder / tube. It seems that they are the original wires. I think I'll get a new set instead of just replacing the holder / tube. It look like BMA has Bosch for $122.49 plus tax. Anyone have a better source? Should I go with something besides Bosch?
