Why is gap critical? The gap is the distance between the center and side electrodes so arcing occurs at the proper voltage that ignites the fuel/air mixture and generates the combustion that makes the engine run.
Large gap = higher voltage requirements/misfire
Smaller gap = A narrow gap may give too small and weak a spark to effectively ignite the fuel-air mixture.
