I'll just add that anything that delivers a "fatter, longer duration, hotter spark", as some plugs and coils claim to do are, in my opinion, snake oil too. Either the fuel/air mixture ignites or it doesn't. If it doesn't ignite, you don't run. If it ignites at all, anything more is total overkill, because once the flame front leaves the area of the spark, which happens almost instantaneously, there's nothing left behind to burn. And, once the mixture IS ignited, the burn is self-sustaining, it needs no spark to keep it going.
