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.
