24 years

19,000 miles

Original AC Delco coils, wires, plugs and injectors.

I am many years older than the car, with far more miles, and except for 1 hip, I still have all of my original parts.

If it's good enough for me, it's good enough for the ZR-1.

If / When I change them, I would use the AC Delco based on the performance of the original parts and on the results of the poll of the Registry Brethren.
Perhaps both would run better with new parts; Then again, perhaps not.
