OK, so I didn't really think apair of plug wires would make any bit of difference at all, But I have to say I bought a set of MSD's and I felt a small difference. I'm surprised, anyone feel the same or is this just in my head?

 

I didn't feel any difference when I swapped on my MSD's, but my stockers were still in good shape. If one or more of your stock wires were worn or had high resistance, I could see how swapping on any new wires would definitely smooth out the way the truck runs
