I'm hoping someone can help me out with this- I'm putting new MSD plug wires on my 502MPI when I add the MSD box this winter. I'm concerned about my ECM or other sensative electrical components. Do I need the heli-core version that supresses electrical interference or can I use the solid core wires? Does MSD make a pre cut set that will fit nicely on my 502MPI? Thanks for the help-

How about ordering merc hi perf blue wires? They fit great and are reasonably priced around 50.00, mine came from Bam. I was very satisfied.
