I am running Lightspeed (probably Plasma II or II+) on top plugs of Lycoming IO-360. I have 4 of the caps that fit threaded (not solid) plugs. Are the stock Lightspeed wires copper core of something else?
 
Got to speak with Klaus Savier at Lightspeed. Very patient. Looks like wires need to be replaced after 5 years. Mine are at least double that. Also they are using a different plug, Denso IK27. Looks like new wires and plugs at 100 hour coming up.
