Interesting discussion about spark plugs taking place on the Egg site. Seems the Eggs are consuming spark plugs at a rather high rate. Jan is recommending spark plug change at 50 hours (3000 miles, automotive).
Haven't seen pictures, but sounds like very high combustion temps and or pressures to wear a plug at this rate. What do you gearheads know about this?
