I wouldn't change them. I would also stick
with the Champion. AS far as I know, plugs don't have age issues like
oil, belts etc. If it ain't broke...

I've owned my car for four years (third owner) and never touched the
plugs. Are these considered a maintenance item which should be changed
periodically or should I just leave well enough alone? I only use the car in
the warmer weather. The most I put on the car would be 1500 miles/year and
it's probably less than that. The car is running fine (maybe a little rough at
idle). I pulled a plug and from what I can tell the plug looks ok. The wires
look pretty clean and new. I did put an electronic ignition in the car when I
got it.
The plugs currently in the car are Champion RJ12YC. Should I change the
plugs? What would you suggest I use? Any benefit to using a higher-end plug
such as NGK Iridium?
Thanks for the advice.
