Can someone give me a definitive answer on what plugs to use in a '48 8N? It has its original 6V system, with front mount distributor.

Between YouTube videos and different sources of parts, there are countless plugs offered. I'd just like a recommendation from someone with plug experience.

Thanks.

I've used Autolite 216/437, Champion H10/H12 and NGK 3112.
All with good results depending on the tractor/engine.
The numbers after the / are one heat range hotter than before it.
I would caution against getting a plug where the threads are too
long or way too short. Other than that, pick you poison.

I have been using Autolite 437 since I got mine 20 years ago. Never had any problems and they are under $2.00 at Napa.
