Yes...NGK-B6HS or its resistor version NGK-BR6HS.
either or is just fine...The "R" only means resistor, won't make any diiference how the plug performs, whatever one you can get...Even if it looks a little longer it shouldnt make any difference in this series of plugs.

If it's the copy of the yd-100, you will have to grind your fins to get anything larger in socket size than a z4-z4c plug in there. Idk if it is, but I have noticed that with the yd-100's and knock offs.
I just went and bought one It is longer it’s the same size as the b7hs that I had but didn’t put in because I was worried about clearance issues with the top of the piston hitting the plug
That wasnt the case for me...NGK always worked well for me in any motor i have ever run on these china girls...just gap at .025...never trust anyones pre-gap...DAMIEN
I have 1 b7hs and 2 br6hs plugs did you try more than one br6?I would highly recommend an E3.32, my engine runs so much smoother with it. The ngk br6hs I bought made it run worse than the stock one.
You shouldnt have any clearence issue as this is the recommended replacement for the Z-4 and Z-8 series plugs...(.025 plug gap)
