    Its kinnda off topic but you could you make a spark plug spark by puttng wires off a car battery to them, Ive seen people do it and just wondering btw I do know they will wear out like this and the spark plug isent going in a engine.

    You need the higher voltage from a coil to do a relly good spark with low current. Doing it strait from the battery, If it jumped the gap, it would almost be like shorting the battery. I think everything would get pretty hot pretty quick. Lots of curretn available. 12 volts isnt very much voltage, Probably wouldnt spark very well.
