I keep exploring on line and finding more info about what might be going on with these coils.
It seems it's important to have a pair of them working in harmony:
go to here
and scroll almost to the bottom of the page to where it says in RED letters "Secret 5 continuation..."
we're not trying to get or use a spark, and I'm not sure if our coils are perpendicular or parallel (or if it matters), but we are trying to get some alignment or resonance happening in the fluids (air, fuel, coolant), and if the resonances or alignments happen correctly, we should see a fairly significant increase in efficiency. each system would require custom tuning, so I would advise against the superglue and baking soda installation until you've fine tuned things.
