[PMD1969]

I pulled a set of plugs off of mine that were over 20 years old and were still "plugging away". We've owned the car since new so its hard to say if they were original to the car but I do know they were at least that old.

This car has been the most reliable car we've ever had. Outside of a leaking oil pan roasting the starter, as soon as the gas hits the engine it fires and runs. Maybe not to the top of tune but it will get you there.

I still run the AC ringed plugs that look somewhat similar to the old style. I also have four or five sets of the originals that look brand new. One of the early sets of originals that I had bought back 10 years ago were still banging away with no issues. I do pull them and check for gap and any bad coloration but then just clean them up a touch and pout them back.
