Review on Enhance Performance with MSD 32829 Super Conductor Spark Plug Wire Set - 8.5mm Thickness, 12 Inches Length by Rudy Hilmy

Wires are slightly longer than stock wires on my 2001 Yukon. On the driver's side, the third cable was rubbing against the steering shaft at the back. I was able to rotate the cable to avoid friction, but this resulted in the cable being closer to the exhaust manifold than I wanted. They worked fine for about a week. The car started to run rough when my wife left town. She took it to the dealer and they found that two of the wires were damaged. They saw no damage, but the measured resistance was out of specification. They replaced the kit and the car has been running flawlessly ever since. I returned the kit for a refund. I had no problems with the return.
