will do but plug wires brand new Belden wire core

Since plug wires are new, they are probably OK, unless the spark is finding a path where they connect to the coil. dirt or grease on the surface of the coil can neatly conduct spark over the insulation to ground, so inspect that carefully as you swap coils. Most often you can’t see where the spark is going on bad coils due to bad internal insulation letting spark jump to the core laminations.
