It took 1.5 hours to do the job. That including "admiration" pauses.
The plugs were sooty on the threads and the insulator was tan with some soot. Unless something changes, I am going to go to the hotter plugs next change. I also waited way past the 16,000 mile plug change interval. It was unnecessary at that time, and I feel that, with the improved running I noticed today after doing the plugs, perhaps the best time would be around 20,000 miles.
