Z4c cross referrence????

My engine uses the Z4C spark-plug. I found this site http://www.sinosparkplugs.com/Replacementchart.htm
but it lists multiple plugs for each brand which leaves me questioning which one is right. I think I might want a plug 1 range cooler than stock since this is Arizona and the beginning of our super hot season.

Oh and I searched here and Z4C returns nothing. Thanks guys.

What engine is it? If it's a typical Chinese 48cc or 66cc, an NGK B6HS is a suitable replacement.

It is a 60cc engine from livefast motors. It looks to be a typical Chinese motor but idk.

I found my original plug today, (the one that came with my kit). It was a Z4C too, so it'll be fine to use an NGK B6HS or B5HS as I do. (The B6HS is slightly cooler.)

Are you sure your engine is 60cc and not 66cc?

Thank you so much Steve.

60 or 66 cc...I don't really know. Livefast motors advertised it as a 60cc engine. I guess I have to take their word that it is a 60cc engine.

I only asked about capacity because most engines are either 48cc or 66cc. I see that LiveFastMotors sell a 48cc, 60cc and 70cc. I assume the 70cc is a 66cc.
Out of interest, I just contacted LiveFast for the bore and stroke of the 60cc engine.

If they actually know and respond I would be interested to know as well.

LiveFastMotors got back to me today. They don't have bore and stroke info for the 60cc engine, but will try to get it.

 

[raattlerviper]

I wonder how they know what to sell the engines as?

 

[AussieSteve]

Possibly by weight, like apples.
