Jon,
There are engines in the lab that use a laser (through a quartz
window) that ignites the fuel 1,000 times better than an old
fashioned electric spark plug. They've gotten interesting results,
maybe 15-20% better than the best 2006 stuff. Significant, but
costly and impractical at this point. More DOE stuff.
The most efficient production gasoline engine was the 3 cyl,
1,000 cc engine in the Honda Insight. That was in 2004.
When you replace a plug, you should use the same part number.
There are 4 different part numbers - for gap clocking.
The plugs are very expensive but good for 105,000 miles.
How's that for some useless trivia?
Have fun everyone,
Bryan
