still dont agree bigger is not hotter spark/better spark ,with the epoxy / oil filled coils all the advantage can be is cooling.all coils are not the same , resistance ,saturation time etc.oil filled is old hat for coils and epoxy filled are compact and stay cooler .most of the cars made in the last 20 years that came with crank fire systems stock have enough mv to cook a man from the inside out,they are not large coils.they are coil over packs (small).i would like to know what the output voltages are on those huge coils that came from the 2nd jen(made in the 80's) and are they oil or epoxy filled,my bet is i can find smaller coils with the same if not more output voltage and less saturation time .
