Gapping is sort of a "mess around with" type of thing. Basically, boost, n2o, high compression, and rich running engines benefit from a closer plug gap because there is less distance for the spark to travel, making it less likely to miss. Hotter plugs have less material and maintain a higher overall temp to keep the electrode and ground strap clean, while cooler plugs have more material and resist detonation, and pre ignition. All of this stuff is "tuning" type of stuff, so play around with it untill you figure out what works
