I’m going to put a new full set of spark plugs on my O-200 in my ‘76 C150M. I’m debating on going with massive electrodes all around, as they’re still much lower in resistance than the Champions that are in there now, or going with fine wires all around. Massive electrodes are $27.50 each; fine wires are $87.50 each, so I was strongly considering massive a on top and fine wires on the bottom. This is relatively common, but I’m curious if anyone here has any additional advice. If I was wealthy I would just buy 8 of the pricey ones and 8 of the cheap ones and have my butler compare them while I fly around in some other expensive airplane. I’m not wealthy. Thanks for any tips or helpful suggestions.
