This is unknown territory but here are a few facts:
The larger the gap, the more load on the stock coils, furthermore, going on the smaller side of gap probably won't hurt the power at all.
Water content in the spray slows the flame and increases spark lag behaving similar to ign retard, also a slower flame front can actually increase the chances of knock.
Colder plugs prevent preignition but can load up at lower loads (BPR9ES work fine on my car at 30 psi gapped 0.022).
