What are the recommended NGK and Champion equivalent plugs best for an unmodified 1970 T120?

Thanks

Mark

CHAMPION N3, WHICH IS NOW THE COPPER CORE N3C. I'VE NEVER USED ANYTHING ELSE, AND I'VE ALWAYS HAD GOOD LUCK WITH THEM IN ALL THE TRIUMPHS I'VE HAD, OVER THE YEARS.

Mine seems to run the best on NKG B7ES. About 1/2 step hotter than N3C's.

Everything will be alright in the end.
If its not alright, its not the end.

Agreed.......90K miles on NGK B7ES. No problems.

I've found N3C to work best.

They are cheap enough, you could buy one set of each, do a tankful of gas with each set, and draw your own real-world conclusion.

Good plan GPZ. Not sure what fuel you get over there? I don't think the octane rating is the same as here........ Regular is unleaded 95 octane and super is usually 97 octane. Shell and BP do an 'ultra' which I think is 98, then Tesco (like Walmart) are now offering 99 octane.
Current price here for ultra and super is $2 PER LITRE, regular is about $1.85 per litre :???:

TRI-AL

I actually have Autolite equivalents to the Champions. They've been in going on 3 yrs now with no problems. Can't recall the # right now, but they're pretty good. :hammer:
