The wires are likely original - it's probably time @ 17 years and 254K km. No misfires though.
Are Denso plugs better than NGK?

Are Denso plugs better than NGK?
looks about .080 from here
Looking at the spark plugs for your 2007 Grand Caravan, the Denso Iridium TT seems to be the best choice. They will last the longest
NGK has the Iridium IX, but they don't last as long as the Laser Iridium. There is also no ruthenium listed.
Denso has the Iridium Power (similar to the NGK IX), but they don't have their equivalent Iridium Long Life (equivalent to the NGK Laser) However, the TT is also supposed to be good for at least 160k km
Denso and NGK are both good plugs, but for your car, the Denso TT is the only long-life iridium available for your car. For a transverse V6 minivan, iridium is a must!
The NGK wires are numbered, and they come in a snazzy blue color
That is a waste-fire system. It should have double precious metal plugs because half of the plugs will wear on the ground side. This appears to have happened to the one that you pulled out as the inside of the ground electrode is hollowed out.
Plastic radiators are not repairable. I'm glad you didn't haul your radiator across town to find that out. After about 15 years the plastic becomes brittle and cracks. This seems to be independent of whether it is OEM or any brand replacement. 15 years and done.

In that case, it's definitely time - I don't want to stress the coil pack.
Clean the condenser!
It (and the old rad) were surprisingly clean.
I didn't know it was a waste-spark system - thank you!
I wondered if the iridium pad was missing off the ground electrode, but a photo of the same (new) plug shows that same indentation where the pad would be.
Now I'm leaning toward replacing the plugs regardless. It's a pushrod engine, so the rear bank is not too hard.
Not trying to be argumentative- I don't think one can make such a blanket statement. None of my plastic radiators have failed and several were over 15 yrs. The one in wife's toyota is 20 yrs and going strong @160k , and 08 Honda V6 still good

Rock Auto forgot the magnet, but I found a used cat in the box!
Changed out the plugs and plug wires.
The old plugs looked pretty good, with consistent gaps under 0.060" (as measured approximately with the tapered wheel gauge) and no oil fouling. The best reason to change them was to have the proper double-precious metal electrodes, which are best for a wasted-spark system, so I'm glad did them for that reason alone.
The new wire set looks great, and appears to be well-made. The numbering threw me for a loop - I installed the #1 and #3 wires on the front bank (L), but found the #5 wire to be too short. Arg! But then I found that the #6 wire fit fine.
Time to call up the firing order! Several on-line diagrams showed that the front (L) bank is numbered #2, #4, and #6, and the rear (R) bank is numbered #1, #3, and #5. This caught me off guard - I guess I was long-conditioned by working on Chevy and Mopar V8s back in the day. (I recall that Ford had weird numbering - 1 to 4 on the R side front to back, and 5 to 8 on the L side, but I didn't work on them often.)
I presumed that when a longitudinal engine is turned sideways (transversely) that the former L back becomes the front bank. Live and learn.
The engine started easily and ran smoothly, as before. I'm hoping for a little bump in gas mileage.
