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

Installation was easy and they fit like an OEM. I was able to leave the heat shields on (some people said they had to remove the heat shields). I didn't notice any improvement in fuel consumption (I also changed the spark plugs to NGK brands), but the truck runs much better. I waited too long before changing spark plugs and wires. Chevy Silverado 2500 HD 6.0LA UPDATE April 2021: Just had to tweak my truck. In just FOUR years on my truck, three of the eight wires fell apart when the mechanic was removing them. GARBAGE! You have less than 50,000 km. I will be using ACDelco parts from now on.
