I have found in the loft some old boxes empty of Champion sparks plugs N3 OEM number 801.
And now I can find champion N3C in Spain, but with the OEM number 086.
Are they the same item that the olds N3C, in all their range?

Back in the early '70s, the available spark plugs were N3, and those were what was specified in my Chilton BSA Repair and Tune-Up Guide.

After a while, N3s were no longer available in the auto supply stores and had been more or less replaced by N3C. So I have to believe that they are the same, or at least close enough to be compatible. I've run Champion N3Cs in my A65s ever since.

As tested at MIRA in UK by Triumph Corp. N3 is colder than a B8ES.

I have no trouble finding blister carded N3Cs in the lawnmower section anywhere. Go figure.

Many NGK have a small notch in the center electrode…My race and street bikes and vehicles have no problems with them..Over the years I never noticed any difference between brands of spark plugs of the correct heat range in any engine..
