I had a set of the aforementioned BCPR6EP-11s in for two years until last
year, which for me is 30,000 miles. The elctrode gap had eroded to 1.27mm
from 1.1mm. These plugs are in a cabinet in my basement. I keep them all
for reference.

I spend most of my time on the highway at or near 4,000 rpm, and have had
to go to the cooler plug to prevent overheating of the insulator.
