Is there any indicator that says it is better to use a cold plug versus a hot
one? How about after rebuilding the engine? After installing electronic
My suggestion for your 6 is to try good old Champion N9Y, N9YC or RN9YC (if
you want resistor plugs). N12Y (and it's variants) plugs are hotter - better
for ailing, lower compression motors not rebuilds. My TR6 has had extensive
performance mods and I'm very satisfied with the N9Y's.
