As I wrote before every systems with split V or multiple electrodes (Splitfire: Triple Platinum, NGK: V-Power, Bosch: Platinum+4, Platinum2, etc) or with special metals like iridium or platinum are designed to maintain the gap between poles. Manufacturers would like to make it maintenance-free.
Before you install a new plug you need to set the gap according to engine producer's specification. It is usually between 0,4-1,2 mm depending on the vehicle, the older the vehicle the smaller the specified gap. This is because of the evolution of ignition systems. Later ones have higher power/performance, can produce sparking on larger gap.
Back to the initial gap setting: the tool for that is usually a feeler gauge:
The tolerance of the gap set by this tool is about tenth of a mm. If you use a normal plug the gap increase during the replacement-interval measures maximum 0.1 mm. So by a wrong setting you can generate the same gap increase like the normal wear and you will realize that the engine still starts and runs without any problem. Why? Because the initial gap is calculated backwards: from the maximum allowed gap minus the wear during the replacement-interval.
Multiple or V shaped electrode plugs do not fire more sparking than one at a time. Sparking will only be generated where the smallest the gap between electrodes. Exactly the same as a normal plug does.
I write the whole thing to try to highlight that for normal, everyday use it is not necessary to use the most modern, sophisticated and expensive spark plug.
