Differences between leading and trailing spark plugs??
Is there an actual difference in the plug. I know that the leading plug fires first and all. And the trailing fires second to help efficiently burn all the gas. But i was wondering if there is an actual difference in the plug. Thanks alot. -Jeff

Yes, one burns hotter then the other. With NGK plugs the heat range is backwards then most domestic plugs. Stock you have a 7 and a 9 heat range, 7 is hotter, 9 is 2 steps colder. Most people run 9's all around and that would matter which hole they went into.
