Can I use solid capacitors instead of electrolytic in my builds? Since electrons flow easier across a spark gap as in the spark plugs from a hotter to a cooler electrode and the side electrode extends farther into the combustion chamber, the people who designed ignition systems thought they had the electrons flowing from the battery to the chassis, to the engine, through the spark plug shells and side electrodes, across the gap then up the ignition wires to the distributor.
