Spark plug wire resistance As part of preventive maintenance I replaced my plug wires. I installed MSD 8.5mm super conductor wires. Just out of curiousity I measured the resistance of the old and new wires: stock wires were all around 380 Ohms, the new MSD wires below 30 Ohms..... that's not a typo, it's thirty vs threehundredeighty.... a huge difference but obviously not all that important as the car runs just as good as it did before....no noticeable difference.... nothing wrong with the almost 10 year old stock wires (this is a stock LS1).
