So, Whats the deal on spark plugs? I have a Midwest T-6 that I just put a G-38 in, an old one with a magnito. I decided it needed a new plug and went to the local saw shop and showed them the old one. He got out his conversion book and said "thats a resistor plug and here is the equivalent".

When I ran it, the ailerons twitched and the more throttle I gave it, the harder over they went. I put the old plug back in and the problem went away.

I guess all resistor plugs are not the same... Do they make aircraft plugs?
