E3

[Dwend92]

I prefer to use a E3 plug on 66/80cc flying horse motor but the stock plug is LD Z4C. I've used a NGK B-4L but I prefer the E3 over the brands that I have used. I don't know what the cross reference numbers are, anyone who can provide the information, it would be greatly appreciated thanks.
