      Comments about NGK Iridium IX Spark Plug:

      Very good plug, V-groove puts the spark on the edge of the electrode. consistently ignites chamber faster with more exposure to the mixture. Gave me more power and response than platinum, good cold running, higher heat range than my 2x platinum. I won't use platinum again, I have tried bosch and autolite double platinum. V-power has a better spark, and don't miss at high temps. altho they don't last as long. remember to have the ground elecrode point to inbetween the valves, or favoring the exhaust valve, for better performance.(Usually the strap will be on the bottom pointing up) You might have to buy 2 extra plugs to line all cylinders up best.
