I used it on my 1960's Honda Benly 50 No. C92. I would like to exchange the whole Ignition coil, but unfortunately OEM Parts does not come out, and I do not understand the Aftermarket parts which fit. In addition, because of the integral type which does not separate Ignition coil and Plug cord, I decided to exchange only Plug cord.
1Plug×Quantity as it has 2 cylinders:2pc. I used the Set. The Cable joint is also sold by NGK, but the outside diameter of the joint itself is too thick and a little difficult to use! (I think I can Joint that well). 。 The C92 is a 2-cylinder engine, but it has a 360 degree crank, so the Ignition coil is 1pc. Plug cord also Quantity in the same direction:Since it is 2pc out, NGK's Joint will interfere with it. I was worried so I went with the CFPosh plug cord joint. If you use this joint, the outer diameter is only for the Heat Shrink Tube which is covered at the end.
Conversely, NGK's Power cable may have a different outer diameter. In my case, fortunately, the original Plug cord was thin & the Vintage Style Plug Cord of Guts Chrome that I installed was also thin, so it was just the same outer diameter. At the time of purchase, I was not aware of this part at all, but future buyers may want to be aware of it.
