Eric, you will get a ton of replies on this thread I am sure. But the bottom line is wider gap, more fuel/air exposed to spark->better combustion...up to a point, which you will reach relatively quickly. As rpms increase and mean cylinder pressure increaases, the ingition system will have to push harder to get the spark across that wide gap. At idle, no problem. Also, you will find that the percieved (operant word) life of the plugs will drop. Also, another aside, the rest of your ignition system will ahve to be in top shape to keep up with that size gap. If you must, go back to 55 thousanths, but I don't really think who will be happy with 80 thousanths for very long.

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
