It is time for a new set of spark plugs, 118000 miles. Do I put on new ignition leads? Mine are factory original. Do I adjust the valves now? This is the one job I am avoiding.

Time for new sparkplugs. What else to do?

If you do the plugs, do the leads. If you do the leads, go ahead and do the valve cover gasket and plug gaskets. If you are in that far, adjust the valves. If you are going to that, might as well do the headgasket and that family of little hoses back there, including the PHH. See how this works?

Then let me put it a different way. What would give cause to replace the ignition leads noting that the scheduled maintenance does not refer to them?

Measure the resistance of each lead, and replace if needed.

When I owned my supercharged truck, I changed them at 100K miles..."just because." It made enough of a difference that I have done it as PM at 100K on the two trucks since.

I hate it when that happens. Start with new front pads and end up with a new front axle.

They deteriorate with time, heat, vibration etc. At nearly 120K miles and 10 odd years your's are probably NO where near as good as new ones. Put in a new OEM set (not aftermarket) and you will notice the difference.
An OEM set is dead easy to install - they are all labelled and the exact right length. An aftermarket set will be a PITA and not fit very well, in my experience. OEM isn't much more cash, either.

Agreed. Do the distributor cap and the rotor while you're there as well -- they are cheap and easy to install.
