While reading a few posts, I noticed some differnt opinions on plug wires.<br /><br />Mostly solid/stranded plug wires do not go bad, if they do, it is because of a break down in the wires insulation.<br /><br />Silicone and Carbon loaded wires do break down in time. One of the major causes of these wires to go bad when they are old is due to moving them around. This can crack/break the conductor. The spark may sometimes jump the gap, but it still is creating resistance. This is why sometimes an engine that runs well and is given a new set of plugs doesn't run well afterwards. It is because of old wires being repositioned causing the silcone/carbon to break within the inslulation.<br /><br />It is best to use an ohm meter to read out the wires. Compare the long wires to long wires and the vice versa with the shorter ones. The length of the wire can give a different resistance.<br /><br />Solid/Stranded wire to me is the best. It is almost impossible for them to go bad. If they do, it is at the end of the wire where the metal clips fasten to the conductor.<br /><br />The more high temperture the wires endure will cause the breakdown faster.<br /><br />This was taught to me long ago and thought I would pass it on.
