Re: Spark Plug Gap

Having the gap a little wide probably won't make any difference. If the ignition is marginal it could make starting a little harder, and the spark could thin out at high speed (90 mph+).

As long as you check them the way you should. If you leave them too long they could wear to the point where the gap is too big to start the car. But that would be after many tens of thousands of miles of wear.
